[PATCH v6 2/2] ceph: fix blindly expanding the readahead windows

by xiubli＠redhat.com

From: Xiubo Li <xiubli(a)redhat.com> Blindly expanding the readahead windows will cause unneccessary pagecache thrashing and also will introdue the network workload. We should disable expanding the windows if the readahead is disabled and also shouldn't expand the windows too much. Expanding forward firstly instead of expanding backward for possible sequential reads. Bound `rreq->len` to the actual file size to restore the previous page cache usage. The posix_fadvise may change the maximum size of a file readahead.

[PATCH net 2/3] can: j1939: change j1939_netdev_lock type to mutex

by Marc Kleine-Budde

From: Fedor Pchelkin <pchelkin(a)ispras.ru> It turns out access to j1939_can_rx_register() needs to be serialized, otherwise j1939_priv can be corrupted when parallel threads call j1939_netdev_start() and j1939_can_rx_register() fails. This issue is thoroughly covered in other commit which serializes access to j1939_can_rx_register(). Change j1939_netdev_lock type to mutex so that we do not need to remove GFP_KERNEL from can_rx_register(). j1939_netdev_lock seems to be used in normal contexts where mutex usage is not prohibited.

amdgpu regression in 6.3.4

by Limonciello, Mario

Hi, Sasha's auto-selection backported: commit f3f8f16b10f8 ("drm/amd/display: enable DPG when disabling plane for phantom pipe") from 6.4 into 6.3.y as commit ef6c86d067b4 ("drm/amd/display: enable DPG when disabling plane for phantom pipe") This was bisected down to have caused a regression in both 6.3.4 and 6.3.5: Link: https://gitlab.freedesktop.org/drm/amd/-/issues/2581 The problematic behavior doesn't occur in 6.4-rc4. This is confirmed to fixed on 6.3.y by backporting an additional commit: 82a10aff9428 ("drm/amd/display: Only wait for blank completion if OTG active")|| Can you please backport this to 6.3.y to fix this regression? Thanks!

PEACE BE WITH YOU,

by Mirabel Vicent

PEACE BE WITH YOU, Receiving this message might sound as a surprise to you, please do accept it as a blessing from God made possible through a woman (widow) with a good and sincere heart towards the poor orphans. Through these projects millions will be positively touched as with God nothing is impossible. I have this strong desire to help the poor orphans suffering each day, but this dream cannot be realised as a result of my health, which does not improve, hence I do not know whether I will survive having undergone different surgical operations, which has kept me hospitalized. Right now, life gives me no choice, but to answer the call (death); my prayers each day is to have a place in Heaven. I have suffered a lot as a result of this incurable sickness (terminal cancer)! Above all, I do not have a child as a result of my sterility. The only help I need from you at this point is to be in constant prayers with me as I believe you have an open heart towards the poor orphans and do believe in GOD. I would be so much happy to see that my funds (Eight million Five Hundred United State Dollars) 8.5 Million USD are properly used to help the less privileged etc before leaving this world as this will be a great relieve for me and my soul. This is a huge responsibility, but I pray that God gives you the strength to handle it. You will also be highly recompensated. Therefore, I want you to receive the money and take 30% to take care of yourself and family while 70% should be used basically on humanitarian purposes mostly to orphanages, Motherless babies home, less privileged and disable citizens and widows around the world. Once I get your reply, I will put you in contact with the bank in charge of the transaction in order to start all necessary procedures so as to enable you to have possession of my funds as soon as possible before my next surgical operations. I looking forward to reading from you.( mirabelvicent01(a)gmail.com ) Mrs. Mirabel Vicent..

[PATCH] blk-mq: fix blk_mq_hw_ctx active request accounting

by Tian Lan

From: Tian Lan <tian.lan(a)twosigma.com> The nr_active counter continues to increase over time which causes the blk_mq_get_tag to hang until the thread is rescheduled to a different core despite there are still tags available. kernel-stack INFO: task inboundIOReacto:3014879 blocked for more than 2 seconds Not tainted 6.1.15-amd64 #1 Debian 6.1.15~debian11 "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. task:inboundIORe state:D stack:0 pid:3014879 ppid:4557 flags:0x00000000 Call Trace: <TASK> __schedule+0x351/0xa20 scheduler+0x5d/0xe0 io_schedule+0x42/0x70 blk_mq_get_tag+0x11a/0x2a0 ? dequeue_task_stop+0x70/0x70 __blk_mq_alloc_requests+0x191/0x2e0 kprobe output showing RQF_MQ_INFLIGHT bit is not cleared before __blk_mq_free_request being called. 320 320 kworker/29:1H __blk_mq_free_request rq_flags 0x220c0 b'__blk_mq_free_request+0x1 [kernel]' b'bt_iter+0x50 [kernel]' b'blk_mq_queue_tag_busy_iter+0x318 [kernel]' b'blk_mq_timeout_work+0x7c [kernel]' b'process_one_work+0x1c4 [kernel]' b'worker_thread+0x4d [kernel]' b'kthread+0xe6 [kernel]' b'ret_from_fork+0x1f [kernel]' This issue arises when both bt_iter() and blk_mq_end_request_batch() are iterating on the same request. The leak happens when blk_mq_find_and_get_req() is executed(from bt_iter) before req_ref_put_and_test() gets called by blk_mq_end_request_batch(). And because non-flush request freed by blk_mq_put_rq_ref() bypasses the active request tracking, the counter would slowly leak overtime.
