[PATCH] ACPI: battery: prevent sysfs_add_battery re-entry on rapid events

by GuangFei Luo

When removing and reinserting the laptop battery, ACPI can trigger two notifications in quick succession: - ACPI_BATTERY_NOTIFY_STATUS (0x80) - ACPI_BATTERY_NOTIFY_INFO (0x81) Both notifications call acpi_battery_update(). Because the events happen very close in time, sysfs_add_battery() can be re-entered before battery->bat is set, causing a duplicate sysfs entry error. This patch ensures that sysfs_add_battery() is not re-entered when battery->bat is already non-NULL, preventing the duplicate sysfs creation and stabilizing battery hotplug handling.

[REGRESSION 5.15.y][BISECTED][PATCH 0/1] console hangs at uevents

by Brett A C Sheffield

Commit ee7a69aa38d8 ("fbdev: Disable sysfb device registration when removing conflicting FBs") was backported to 5.15.y LTS. This causes a regression where all virtual consoles stop responding during boot at: "Populating /dev with existing devices through uevents ..." The console is no longer responding, nor is it possible to switch to another virtual console. It is possible to force a reboot with CTRL+ALT+DEL. The system is otherwise still working normally, and can be connected to over ssh. This patch was not backported to 5.4.y or 5.10.y. Newer stable kernels with this patch (6.1.y, 6.6.y, 6.12,y, 6.15.y, 6.16.y) and mainline are unaffected. There are a bunch of patches that touch fbmem.c in later stable kernels, and I started looking at this but it gets messy very quickly as e23a5e14aa27 is a merge commit. Given this was an autoselected patch that was not backported to fix any specific issue the simplest and cleanest fix is to simply revert.

[PATCH] powerpc/64s/radix/kfence: map __kfence_pool at page granularity

by Aboorva Devarajan

From: Hari Bathini <hbathini(a)linux.ibm.com> When KFENCE is enabled, total system memory is mapped at page level granularity. But in radix MMU mode, ~3GB additional memory is needed to map 100GB of system memory at page level granularity when compared to using 2MB direct mapping.This is not desired considering KFENCE is designed to be enabled in production kernels [1]. Mapping only the memory allocated for KFENCE pool at page granularity is sufficient to enable KFENCE support. So, allocate __kfence_pool during bootup and map it at page granularity instead of mapping all system memory at page granularity. Without patch: # cat /proc/meminfo MemTotal: 101201920 kB With patch: # cat /proc/meminfo MemTotal: 104483904 kB Note that enabling KFENCE at runtime is disabled for radix MMU for now, as it depends on the ability to split page table mappings and such APIs are not currently implemented for radix MMU. All kfence_test.c testcases passed with this patch.

[PATCH 5.15] xfs: short circuit xfs_growfs_data_private() if delta is zero

by Amir Goldstein

From: Eric Sandeen <sandeen(a)redhat.com> [ Upstream commit 84712492e6dab803bf595fb8494d11098b74a652 ] Although xfs_growfs_data() doesn't call xfs_growfs_data_private() if in->newblocks == mp->m_sb.sb_dblocks, xfs_growfs_data_private() further massages the new block count so that we don't i.e. try to create a too-small new AG. This may lead to a delta of "0" in xfs_growfs_data_private(), so we end up in the shrink case and emit the EXPERIMENTAL warning even if we're not changing anything at all. Fix this by returning straightaway if the block delta is zero. (nb: in older kernels, the result of entering the shrink case with delta == 0 may actually let an -ENOSPC escape to userspace, which is confusing for users.)

[PATCH v1] arm64: dts: qcom: monaco-evk: Use correct sound card compatible to match SoC

by Mohammad Rafi Shaik

The Monaco-EVK board is based on Qualcomm's QCS8300 SoC. The DTS previously reused the sound card compatible as "qcom,qcs8275-sndcard", which is based on existing coverage. To maintain clarity and consistency, the naming conventions for the compatible should reflect actual SoC rather than the board. Therefore, update the sound card compatible as "qcom,qcs8300-sndcard" to avoid potential confusion.

[PATCH v3 0/3] phy: qcom: edp: Add missing ref clock to x1e80100

by Abel Vesa

According to documentation, the DP PHY on x1e80100 has another clock called ref. The current X Elite devices supported upstream work fine without this clock, because the boot firmware leaves this clock enabled. But we should not rely on that. Also, when it comes to power management, this clock needs to be also disabled on suspend. So even though this change breaks the ABI, it is needed in order to make we disable this clock on runtime PM, when that is going to be enabled in the driver. So rework the driver to allow different number of clocks, fix the dt-bindings schema and add the clock to the DT node as well. Signed-off-by: Abel Vesa <abel.vesa(a)linaro.org> --- Changes in v3: - Use dev_err_probe() on clocks parsing failure. - Explain why the ABI break is necessary. - Drop the extra 'clk' suffix from the clock name. So ref instead of refclk. - Link to v2: https://lore.kernel.org/r/20250903-phy-qcom-edp-add-missing-refclk-v2-0-d88… Changes in v2: - Fix schema by adding the minItems, as suggested by Krzysztof. - Use devm_clk_bulk_get_all, as suggested by Konrad. - Rephrase the commit messages to reflect the flexible number of clocks. - Link to v1: https://lore.kernel.org/r/20250730-phy-qcom-edp-add-missing-refclk-v1-0-6f7… --- Abel Vesa (3): dt-bindings: phy: qcom-edp: Add missing clock for X Elite phy: qcom: edp: Make the number of clocks flexible arm64: dts: qcom: Add missing TCSR ref clock to the DP PHYs .../devicetree/bindings/phy/qcom,edp-phy.yaml | 28 +++++++++++++++++++++- arch/arm64/boot/dts/qcom/x1e80100.dtsi | 12 ++++++---- drivers/phy/qualcomm/phy-qcom-edp.c | 16 ++++++------- 3 files changed, 43 insertions(+), 13 deletions(-) --- base-commit: 65dd046ef55861190ecde44c6d9fcde54b9fb77d change-id: 20250730-phy-qcom-edp-add-missing-refclk-5ab82828f8e7 Best regards, -- Abel Vesa <abel.vesa(a)linaro.org>

[PATCH net 0/3] mptcp: misc fixes for v6.17-rc6

Here are various unrelated fixes: - Patch 1: Fix a wrong attribute type in the MPTCP Netlink specs. A fix for v6.7. - Patch 2: Avoid mentioning a deprecated MPTCP sysctl knob in the doc. A fix for v6.15. - Patch 3: Handle new warnings from ShellCheck v0.11.0. This prevents some warnings reported by some CIs.
