Thai Airways Name Change: A Simple Guide to Correcting Your Flight Details

by 8j42c2cspn＠mrotzis.com

📞 For the fastest help, call Thai Airways customer support at 1-866-284-3022. Their agents are trained to assist with name corrections. ✍️ Did you book a flight with Thai Airways and realize your name is misspelled or needs updating? Whether it is a minor typo or a legal name change, it is essential to correct your flight details before travel to avoid problems at check-in. Fortunately, Thai Airways offers options for name changes or corrections — and we are here to guide you through the process, step by step. 📌 Why Name Corrections Matter Airlines require that the name on your ticket exactly matches the name on your government-issued ID or passport. Even a small typo can result in: ❌ Denied boarding ❌ TSA security issues ❌ Non-refundable tickets going to waste That is why it is important to act quickly if you notice an error. 👉 Pro Tip: As soon as you spot an issue with your name, call 1-866-284-3022 to fix it directly with Thai Airways. 📋 Thai Airways Name Correction Policy: The Basics Thai Airways does allow name corrections and changes, but there are specific rules based on the type and extent of the correction. ✏️ Minor Name Corrections If your correction is minor (e.g., spelling mistake, missing middle name, or nickname to legal name), it is usually easy to fix. Examples: • “Jonh” to “John” • “Liz” to “Elizabeth” • Missing middle name or incorrect initials 🟢 These are typically allowed once per passenger. Call 📞 1-866-284-3022 to request a minor correction. You may need to provide identification or legal documentation. 🔄 Major Name Changes For legal name changes due to: • Marriage 👰 • Divorce 💔 • Legal court order 📄 You will likely be required to submit legal documents (e.g., marriage certificate, divorce decree, or court papers). Important: Name changes are different from transferring your ticket to someone else — Sun Country does not allow name transfers. The passenger must remain the same person. 📞 For clarity and assistance, it is best to speak to a representative at 1-866-284-3022. 💰 Are There Any Fees for Name Changes? Yes, in most cases, Sun Country charges a name change or correction fee, which may vary depending on: • The type of fare you purchased • How close it is to your departure date • Whether the change is made online or via customer service Fees can range from $75 to $150, though minor corrections may be less, especially if made within 24 hours of booking. 🎯 To get an accurate quote and understand your options, call 1-866-284-3022 and speak with a Sun Country agent. 🌐 How to Request a Name Correction There are two main ways to request a name correction on your Thai Airways ticket: ✅ 1. Call Customer Support (Recommended) 📞 Dial 1-866-284-3022 📄 Provide your confirmation number, full incorrect name, and the correct name 🧾 Have a valid ID or legal document ready, if needed 🎟️ The agent will process the change and send you an updated itinerary Calling ensures faster processing and personalized help. 💻 2. Manage Booking Online While not all name changes can be made online, you can attempt to: 1. Visit official Sun Country website 2. Click on "My Trips" 3. Enter your last name and confirmation code 4. Look for an option to edit passenger details 📌 If you cannot make changes online, revert to calling 📞 1-866-284-3022. ⏱️ Time-Sensitive Corrections: Act Fast! If your flight is within 24 to 48 hours, do not delay. Last-minute changes can be harder to process and may result in additional fees or denied boarding. 🚨 Urgent situations? Call 📞 1-866-284-3022 immediately. Sun Country's support team can walk you through your options quickly. ✍️ Final Checklist Before You Travel ✅ Name on your ticket matches your ID ✅ You've received an updated confirmation email ✅ You've saved all receipts and documents related to the name correction ✅ You have confirmed there are no other errors in your booking (dates, destinations, etc.) 📞 Need Help? Call Thai Airways Anytime Whether you are unsure if your change qualifies or you just want confirmation, don’t hesitate to call Thai Airways at 1-866-284-3022. Their support agents are available to: • Handle name corrections • Answer policy questions • Assist with legal document submissions • Avoid unnecessary delays or cancellations 🧳 In Summary Mistakes happen — but with Thai Airways, correcting a name on your flight reservation does not have to be stressful. The key is to act fast, follow the policy, and use the right contact channels. 🛑 Do NOT ignore a misspelled name 📞 ALWAYS call 1-866-284-3022 for support 📧 Double-check your confirmation email 📅 Fix issues well before your travel date Safe travels — and smooth corrections!

[PATCH 5.10] scsi: target: target_core_configfs: Add length check to avoid buffer overflow

by Andrey Troshin

scsi: target: target_core_configfs: Add length check to avoid buffer overflow A buffer overflow arises from the usage of snprintf to write into the buffer "buf" in target_lu_gp_members_show function located in /drivers/target/target_core_configfs.c. This buffer is allocated with size LU_GROUP_NAME_BUF (256 bytes). snprintf(...) formats multiple strings into buf with the HBA name (hba->hba_group.cg_item), a slash character, a devicename (dev-> dev_group.cg_item) and a newline character, the total formatted string length may exceed the buffer size of 256 bytes. Since snprintf() returns the total number of bytes that would have been written (the length of %s/%sn ), this value may exceed the buffer length (256 bytes) passed to memcpy(), this will ultimately cause function memcpy reporting a buffer overflow error.

Vueling Airlines Name Change Made Easy: A Quick Guide to Updating Your Booking

by 8j42c2cspn＠mrotzis.com

📞 For the fastest help, call Vueling Airlines customer support at 1-866-284-3022. Their agents are trained to assist with name corrections. ✍️ Did you book a flight with Vueling Airlines and realize your name is misspelled or needs updating? Whether it is a minor typo or a legal name change, it is essential to correct your flight details before travel to avoid problems at check-in. Fortunately, Vueling Airlines offers options for name changes or corrections — and we are here to guide you through the process, step by step. 📌 Why Name Corrections Matter Airlines require that the name on your ticket exactly matches the name on your government-issued ID or passport. Even a small typo can result in: ❌ Denied boarding ❌ TSA security issues ❌ Non-refundable tickets going to waste That is why it is important to act quickly if you notice an error. 👉 Pro Tip: As soon as you spot an issue with your name, call 1-866-284-3022 to fix it directly with Vueling Airlines. 📋 Vueling Airlines Name Correction Policy: The Basics Vueling Airlines does allow name corrections and changes, but there are specific rules based on the type and extent of the correction. ✏️ Minor Name Corrections If your correction is minor (e.g., spelling mistake, missing middle name, or nickname to legal name), it is usually easy to fix. Examples: • “Jonh” to “John” • “Liz” to “Elizabeth” • Missing middle name or incorrect initials 🟢 These are typically allowed once per passenger. Call 📞 1-866-284-3022 to request a minor correction. You may need to provide identification or legal documentation. 🔄 Major Name Changes For legal name changes due to: • Marriage 👰 • Divorce 💔 • Legal court order 📄 You will likely be required to submit legal documents (e.g., marriage certificate, divorce decree, or court papers). Important: Name changes are different from transferring your ticket to someone else — Sun Country does not allow name transfers. The passenger must remain the same person. 📞 For clarity and assistance, it is best to speak to a representative at 1-866-284-3022. 💰 Are There Any Fees for Name Changes? Yes, in most cases, Sun Country charges a name change or correction fee, which may vary depending on: • The type of fare you purchased • How close it is to your departure date • Whether the change is made online or via customer service Fees can range from $75 to $150, though minor corrections may be less, especially if made within 24 hours of booking. 🎯 To get an accurate quote and understand your options, call 1-866-284-3022 and speak with a Sun Country agent. 🌐 How to Request a Name Correction There are two main ways to request a name correction on your Vueling Airlines ticket: ✅ 1. Call Customer Support (Recommended) 📞 Dial 1-866-284-3022 📄 Provide your confirmation number, full incorrect name, and the correct name 🧾 Have a valid ID or legal document ready, if needed 🎟️ The agent will process the change and send you an updated itinerary Calling ensures faster processing and personalized help. 💻 2. Manage Booking Online While not all name changes can be made online, you can attempt to: 1. Visit official Sun Country website 2. Click on "My Trips" 3. Enter your last name and confirmation code 4. Look for an option to edit passenger details 📌 If you cannot make changes online, revert to calling 📞 1-866-284-3022. ⏱️ Time-Sensitive Corrections: Act Fast! If your flight is within 24 to 48 hours, do not delay. Last-minute changes can be harder to process and may result in additional fees or denied boarding. 🚨 Urgent situations? Call 📞 1-866-284-3022 immediately. Sun Country's support team can walk you through your options quickly. ✍️ Final Checklist Before You Travel ✅ Name on your ticket matches your ID ✅ You've received an updated confirmation email ✅ You've saved all receipts and documents related to the name correction ✅ You have confirmed there are no other errors in your booking (dates, destinations, etc.) 📞 Need Help? Call Vueling Airlines Anytime Whether you are unsure if your change qualifies or you just want confirmation, don’t hesitate to call Vueling Airlines at 1-866-284-3022. Their support agents are available to: • Handle name corrections • Answer policy questions • Assist with legal document submissions • Avoid unnecessary delays or cancellations 🧳 In Summary Mistakes happen — but with Vueling Airlines, correcting a name on your flight reservation does not have to be stressful. The key is to act fast, follow the policy, and use the right contact channels. 🛑 Do NOT ignore a misspelled name 📞 ALWAYS call 1-866-284-3022 for support 📧 Double-check your confirmation email 📅 Fix issues well before your travel date Safe travels — and smooth corrections!

[PATCH] virtio: vdpa: Fix reference count leak in octep_sriov_enable()

by Miaoqian Lin

pci_get_device() will increase the reference count for the returned pci_dev, and also decrease the reference count for the input parameter from if it is not NULL. If we break the loop in with 'vf_pdev' not NULL. We need to call pci_dev_put() to decrease the reference count.

[PATCH] perf: arm_cspmu: fix device leak in arm_cspmu_impl_unregister

by Ma Ke

arm_cspmu_impl_unregister() utilizes driver_find_device() to locate matching devices. driver_find_device() increments the ref count of the found device by calling get_device(), but arm_cspmu_impl_unregister() fails to call put_device() to decrement the reference count after processing each device. This results in a reference count leak of the device objects, which prevents devices from being properly released and causes a memory leak. Fix the leak by adding put_device() after device_release_driver() in the while loop. Found by code review.

[PATCH] ARM: tegra: fix device leak on tegra ahb lookup

by Ma Ke

tegra_ahb_enable_smmu() utilizes driver_find_device_by_of_node() which internally calls driver_find_device() to locate the matching device. driver_find_device() increments the ref count of the found device by calling get_device(), but tegra_ahb_enable_smmu() fails to call put_device() to decrement the reference count before returning. This results in a reference count leak of the device, which may prevent the device from being properly released and cause a memory leak. Found by code review.

However, if inflating the new page succeeded, we effectively deflated the old page, reducing the balloon size. In that case, the migration actually worked: similar to migrating+ immediately deflating the new page. The old page will be freed back to the buddy. Right now, the core will leave the page be marked as isolated (as we returned an error). When later trying to putback that page, we will run into the WARN_ON_ONCE() in balloon_page_putback(). That handling was changed in commit 3544c4faccb8 ("mm/balloon_compaction: stop using __ClearPageMovable()"); before that change, we would have tolerated that way of handling it. To fix it, let's just return 0 in that case, making the core effectively just clear the "isolated" flag + freeing it back to the buddy as if the migration succeeded. Note that the new page will also get freed when the core puts the last reference. Note that this also makes it all be more consistent: we will no longer unisolate the page in the balloon driver while keeping it marked as being isolated in migration core. This was found by code inspection.

However, following commit 060913999d7a ("mm: migrate: support poisoned recover from migrate folio"), folio_mc_copy() is called before __folio_migrate_mapping(). If the latter fails (-EAGAIN), the copy will be done again to the same destination page. Since copy_highpage() already set the PG_mte_tagged flag, this second copy will warn. Replace the WARN_ON_ONCE(page already tagged) in the arm64 copy_highpage() with a comment.

The current logic uses !PTR_ERR_OR_ZERO(cpu_clk) which evaluates to true for both valid pointers and NULL, leading to potential NULL pointer dereference in clk_get_rate(). Per include/linux/err.h documentation, PTR_ERR_OR_ZERO(ptr) returns: "The error code within @ptr if it is an error pointer; 0 otherwise." This means PTR_ERR_OR_ZERO() returns 0 for both valid pointers AND NULL pointers.

Please apply commit d88a8bb8bbbe ("Bluetooth: btintel: Add DSBR support for BlazarIW, BlazarU and GaP") to 6.12.y

by Salvatore Bonaccorso

Hi Guido Berhoerster asked in Debian (https://bugs.debian.org/1118660) to consider adding support for bluetooth device of BlazarIW, BlazarU and Gale Peak2 cores, which landed in 6.13-rc1, via d88a8bb8bbbe ("Bluetooth: btintel: Add DSBR support for BlazarIW, BlazarU and GaP"). While it is not exactly a bugfix, as things were not working beforehand as well, this type of hardware might be very common during the lifecycle of users for 6.12.y stable series. Can you consider picking the commit for 6.12.y? Regards, Salvatore

But for various reasons, the ADD_ADDR could be sent after the "4th ACK", and the special case doesn't work. On NIPA, the new test validating this special case for the C-flag failed a few times, e.g. 102 default limits, server deny join id 0 syn rx [FAIL] got 0 JOIN[s] syn rx expected 2 Server ns stats (...) MPTcpExtAddAddrTx 1 MPTcpExtEchoAdd 1 Client ns stats (...) MPTcpExtAddAddr 1 MPTcpExtEchoAddTx 1 synack rx [FAIL] got 0 JOIN[s] synack rx expected 2 ack rx [FAIL] got 0 JOIN[s] ack rx expected 2 join Rx [FAIL] see above syn tx [FAIL] got 0 JOIN[s] syn tx expected 2 join Tx [FAIL] see above I had a suspicion about what the issue could be: the ADD_ADDR might have been received after the switch to the 'fully-established' state. The issue was not easy to reproduce. The packet capture shown that the ADD_ADDR can indeed be sent with a delay, and the client would not try to establish subflows to it as expected. A simple fix is not to mark the endpoints as 'used' in the C-flag case, when looking at creating subflows to the remote initial IP address and port. In this case, there is no need to try. Note: newly added fullmesh endpoints will still continue to be used as expected, thanks to the conditions behind mptcp_pm_add_addr_c_flag_case.

[PATCH v2 RESEND] net/dccp: validate Reset/Close/CloseReq in DCCP_REQUESTING

by Yizhou Zhao

DCCP sockets in DCCP_REQUESTING state do not check the sequence number or acknowledgment number for incoming Reset, CloseReq, and Close packets. As a result, an attacker can send a spoofed Reset packet while the client is in the requesting state. The client will accept the packet without verification and immediately close the connection, causing a denial of service (DoS) attack. This patch moves the processing of Reset, Close, and CloseReq packets into dccp_rcv_request_sent_state_process() and validates the ack number before accepting them. This fix should apply to stable versions *only* in Linux 5.x and 6.x. Note that DCCP was removed in Linux 6.16, so this patch is only relevant for older versions. We tested it on Ubuntu 24.04 LTS (Linux 6.8) and it worked as expected.

We should use RB_CLEAR_NODE() set the erased node to EMPTY, then pde_subdir_next() will return NULL to avoid uaf access. We found an uaf issue while using stress-ng testing, need to run testcase getdent and tun in the same time. The steps of the issue is as follows: 1) use getdent to traverse dir /proc/pid/net/dev_snmp6/, and current pde is tun3; 2) in the [time windows] unregister netdevice tun3 and tun2, and erase them from rbtree. erase tun3 first, and then erase tun2. the pde(tun2) will be released to slab; 3) continue to getdent process, then pde_subdir_next() will return pde(tun2) which is released, it will case uaf access.

[PATCH] drivers: Fix reference leak in altr_sysmgr_regmap_lookup_by_phandle()

by Ma Ke

altr_sysmgr_regmap_lookup_by_phandle() utilizes driver_find_device_by_of_node() which internally calls driver_find_device() to locate the matching device. driver_find_device() increments the ref count of the found device by calling get_device(), but altr_sysmgr_regmap_lookup_by_phandle() fails to call put_device() to decrement the reference count before returning. This results in a reference count leak of the device, which may prevent the device from being properly released and cause a memory leak. Found by code review.

[PATCH v2 fs/btrfs v2] btrfs: fix memory leak of qgroup_list in btrfs_add_qgroup_relation

by Shardul Bankar

When btrfs_add_qgroup_relation() is called with invalid qgroup levels (src >= dst), the function returns -EINVAL directly without freeing the preallocated qgroup_list structure passed by the caller. This causes a memory leak because the caller unconditionally sets the pointer to NULL after the call, preventing any cleanup. The issue occurs because the level validation check happens before the mutex is acquired and before any error handling path that would free the prealloc pointer. On this early return, the cleanup code at the 'out' label (which includes kfree(prealloc)) is never reached. In btrfs_ioctl_qgroup_assign(), the code pattern is: prealloc = kzalloc(sizeof(*prealloc), GFP_KERNEL); ret = btrfs_add_qgroup_relation(trans, sa->src, sa->dst, prealloc); prealloc = NULL; // Always set to NULL regardless of return value ... kfree(prealloc); // This becomes kfree(NULL), does nothing When the level check fails, 'prealloc' is never freed by either the callee or the caller, resulting in a 64-byte memory leak per failed operation. This can be triggered repeatedly by an unprivileged user with access to a writable btrfs mount, potentially exhausting kernel memory. Fix this by freeing prealloc before the early return, ensuring prealloc is always freed on all error paths. Fixes: 8465ecec9611 ("btrfs: Check qgroup level in kernel qgroup assign.")

by Andrew Morton

The patch titled Subject: mm/huge_memory: preserve PG_has_hwpoisoned if a folio is split to >0 order has been added to the -mm mm-hotfixes-unstable branch. Its filename is mm-huge_memory-preserve-pg_has_hwpoisoned-if-a-folio-is-split-to-0-order.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patche… This patch will later appear in the mm-hotfixes-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Zi Yan <ziy(a)nvidia.com> Subject: mm/huge_memory: preserve PG_has_hwpoisoned if a folio is split to >0 order Date: Wed, 22 Oct 2025 23:05:21 -0400 folio split clears PG_has_hwpoisoned, but the flag should be preserved in after-split folios containing pages with PG_hwpoisoned flag if the folio is split to >0 order folios. Scan all pages in a to-be-split folio to determine which after-split folios need the flag. An alternatives is to change PG_has_hwpoisoned to PG_maybe_hwpoisoned to avoid the scan and set it on all after-split folios, but resulting false positive has undesirable negative impact. To remove false positive, caller of folio_test_has_hwpoisoned() and folio_contain_hwpoisoned_page() needs to do the scan. That might be causing a hassle for current and future callers and more costly than doing the scan in the split code. More details are discussed in [1]. This issue can be exposed via: 1. splitting a has_hwpoisoned folio to >0 order from debugfs interface; 2. truncating part of a has_hwpoisoned folio in truncate_inode_partial_folio(). And later accesses to a hwpoisoned page could be possible due to the missing has_hwpoisoned folio flag. This will lead to MCE errors.

[PATCH V2] LoongArch: Align ACPI structures if ARCH_STRICT_ALIGN enabled

ARCH_STRICT_ALIGN is used for hardware without UAL, now it only control the -mstrict-align flag. However, ACPI structures are packed by default so will cause unaligned accesses.

[PATCH v3 06/14] iommu/mediatek: fix use-after-free on probe deferral

by Johan Hovold

The driver is dropping the references taken to the larb devices during probe after successful lookup as well as on errors. This can potentially lead to a use-after-free in case a larb device has not yet been bound to its driver so that the iommu driver probe defers.

[PATCH v2 6.1.y] drm/amdgpu: Fix potential out-of-bounds access in 'amdgpu_discovery_reg_base_init()'

From: Srinivasan Shanmugam <srinivasan.shanmugam(a)amd.com> commit cdb637d339572398821204a1142d8d615668f1e9 upstream. The issue arises when the array 'adev->vcn.vcn_config' is accessed before checking if the index 'adev->vcn.num_vcn_inst' is within the bounds of the array.

[PATCH v2 0/4] arm64: dts: marvell: cn913x-solidrun: fix sata ports status

by Josua Mayer

The SolidRun CN9130 SoC based boards have a variety of functional problems, in particular - SATA ports - CN9132 CEX-7 eMMC - CN9132 Clearfog PCI-E x2 / x4 ports are not functional.

[PATCH bpf-next 1/3] ftrace: Fix BPF fexit with livepatch

by Song Liu

When livepatch is attached to the same function as bpf trampoline with a fexit program, bpf trampoline code calls register_ftrace_direct() twice. The first time will fail with -EAGAIN, and the second time it will succeed. This requires register_ftrace_direct() to unregister the address on the first attempt. Otherwise, the bpf trampoline cannot attach. Here is an easy way to reproduce this issue: insmod samples/livepatch/livepatch-sample.ko bpftrace -e 'fexit:cmdline_proc_show {}' ERROR: Unable to attach probe: fexit:vmlinux:cmdline_proc_show... Fix this by cleaning up the hash when register_ftrace_function_nolock hits errors.

However, on AMD systems, only a limited number of RMIDs are guaranteed to be actively tracked by the hardware. RMIDs that exceed this limit are placed in an "Unavailable" state. When a bandwidth counter is read for such an RMID, the hardware sets MSR_IA32_QM_CTR.Unavailable (bit 62). When such an RMID starts being tracked again the hardware counter is reset to zero. MSR_IA32_QM_CTR.Unavailable remains set on first read after tracking re-starts and is clear on all subsequent reads as long as the RMID is tracked. resctrl miscounts the bandwidth events after an RMID transitions from the "Unavailable" state back to being tracked. This happens because when the hardware starts counting again after resetting the counter to zero, resctrl in turn compares the new count against the counter value stored from the previous time the RMID was tracked. This results in resctrl computing an event value that is either undercounting (when new counter is more than stored counter) or a mistaken overflow (when new counter is less than stored counter). Reset the stored value (arch_mbm_state::prev_msr) of MSR_IA32_QM_CTR to zero whenever the RMID is in the "Unavailable" state to ensure accurate counting after the RMID resets to zero when it starts to be tracked again. Example scenario that results in mistaken overflow ================================================== 1. The resctrl filesystem is mounted, and a task is assigned to a monitoring group. $mount -t resctrl resctrl /sys/fs/resctrl $mkdir /sys/fs/resctrl/mon_groups/test1/ $echo 1234 > /sys/fs/resctrl/mon_groups/test1/tasks $cat /sys/fs/resctrl/mon_groups/test1/mon_data/mon_L3_*/mbm_total_bytes 21323 <- Total bytes on domain 0 "Unavailable" <- Total bytes on domain 1 Task is running on domain 0. Counter on domain 1 is "Unavailable". 2. The task runs on domain 0 for a while and then moves to domain 1. The counter starts incrementing on domain 1. $cat /sys/fs/resctrl/mon_groups/test1/mon_data/mon_L3_*/mbm_total_bytes 7345357 <- Total bytes on domain 0 4545 <- Total bytes on domain 1 3. At some point, the RMID in domain 0 transitions to the "Unavailable" state because the task is no longer executing in that domain. $cat /sys/fs/resctrl/mon_groups/test1/mon_data/mon_L3_*/mbm_total_bytes "Unavailable" <- Total bytes on domain 0 434341 <- Total bytes on domain 1 4. Since the task continues to migrate between domains, it may eventually return to domain 0. $cat /sys/fs/resctrl/mon_groups/test1/mon_data/mon_L3_*/mbm_total_bytes 17592178699059 <- Overflow on domain 0 3232332 <- Total bytes on domain 1 In this case, the RMID on domain 0 transitions from "Unavailable" state to active state. The hardware sets MSR_IA32_QM_CTR.Unavailable (bit 62) when the counter is read and begins tracking the RMID counting from 0. Subsequent reads succeed but return a value smaller than the previously saved MSR value (7345357). Consequently, the resctrl's overflow logic is triggered, it compares the previous value (7345357) with the new, smaller value and incorrectly interprets this as a counter overflow, adding a large delta. In reality, this is a false positive: the counter did not overflow but was simply reset when the RMID transitioned from "Unavailable" back to active state. Here is the text from APM [1] available from [2]. "In PQOS Version 2.0 or higher, the MBM hardware will set the U bit on the first QM_CTR read when it begins tracking an RMID that it was not previously tracking. The U bit will be zero for all subsequent reads from that RMID while it is still tracked by the hardware. Therefore, a QM_CTR read with the U bit set when that RMID is in use by a processor can be considered 0 when calculating the difference with a subsequent read."

You may need to provide identification or legal documentation. 🔄 Major Name Changes For legal name changes due to: • Marriage 👰 • Divorce 💔 • Legal court order 📄 You will likely be required to submit legal documents (e.g., marriage certificate, divorce decree, or court papers). Important: Name changes are different from transferring your ticket to someone else — Sun Country does not allow name transfers.

Everything You Need to Know About Changing Your Name on Caribbean Airlines Bookings

by 6s8o81mzm0＠zudpck.com

📞 For the fastest help, call Caribbean Airlines customer support at 1-866-284-3022. Their agents are trained to assist with name corrections. ✍️ Did you book a flight with Caribbean Airlines and realize your name is misspelled or needs updating? Whether it is a minor typo or a legal name change, it is essential to correct your flight details before travel to avoid problems at check-in. Fortunately, Caribbean Airlines offers options for name changes or corrections — and we are here to guide you through the process, step by step. 📌 Why Name Corrections Matter Airlines require that the name on your ticket exactly matches the name on your government-issued ID or passport. Even a small typo can result in: ❌ Denied boarding ❌ TSA security issues ❌ Non-refundable tickets going to waste That is why it is important to act quickly if you notice an error. 👉 Pro Tip: As soon as you spot an issue with your name, call 1-866-284-3022 to fix it directly with Caribbean Airlines. 📋 Caribbean Airlines Name Correction Policy: The Basics Caribbean Airlines does allow name corrections and changes, but there are specific rules based on the type and extent of the correction. ✏️ Minor Name Corrections If your correction is minor (e.g., spelling mistake, missing middle name, or nickname to legal name), it is usually easy to fix. Examples: • “Jonh” to “John” • “Liz” to “Elizabeth” • Missing middle name or incorrect initials 🟢 These are typically allowed once per passenger. Call 📞 1-866-284-3022 to request a minor correction. You may need to provide identification or legal documentation. 🔄 Major Name Changes For legal name changes due to: • Marriage 👰 • Divorce 💔 • Legal court order 📄 You will likely be required to submit legal documents (e.g., marriage certificate, divorce decree, or court papers). Important: Name changes are different from transferring your ticket to someone else — Sun Country does not allow name transfers. The passenger must remain the same person. 📞 For clarity and assistance, it is best to speak to a representative at 1-866-284-3022. 💰 Are There Any Fees for Name Changes? Yes, in most cases, Sun Country charges a name change or correction fee, which may vary depending on: • The type of fare you purchased • How close it is to your departure date • Whether the change is made online or via customer service Fees can range from $75 to $150, though minor corrections may be less, especially if made within 24 hours of booking. 🎯 To get an accurate quote and understand your options, call 1-866-284-3022 and speak with a Sun Country agent. 🌐 How to Request a Name Correction There are two main ways to request a name correction on your Caribbean Airlines ticket: ✅ 1.

Look for an option to edit passenger details 📌 If you cannot make changes online, revert to calling 📞 1-866-284-3022. ⏱️ Time-Sensitive Corrections: Act Fast!

[PATCH] ARM: dts: nxp: imx6ul: correct SAI3 interrupt line

by Maarten Zanders

The i.MX6UL reference manual lists two possible interrupt lines for SAI3 (56 and 57, offset +32). The current device tree entry uses the first one (24), which prevents IRQs from being handled properly. Use the second interrupt line (25), which does allow interrupts to work as expected.
