[PATCH AUTOSEL 5.10 01/10] rcu: Back off upon fill_page_cache_func() allocation failure

by Sasha Levin

From: Michal Hocko <mhocko(a)suse.com> [ Upstream commit 093590c16b447f53e66771c8579ae66c96f6ef61 ] The fill_page_cache_func() function allocates couple of pages to store kvfree_rcu_bulk_data structures. This is a lightweight (GFP_NORETRY) allocation which can fail under memory pressure. The function will, however keep retrying even when the previous attempt has failed. This retrying is in theory correct, but in practice the allocation is invoked from workqueue context, which means that if the memory reclaim gets stuck, these retries can hog the worker for quite some time. Although the workqueues subsystem automatically adjusts concurrency, such adjustment is not guaranteed to happen until the worker context sleeps. And the fill_page_cache_func() function's retry loop is not guaranteed to sleep (see the should_reclaim_retry() function). And we have seen this function cause workqueue lockups: kernel: BUG: workqueue lockup - pool cpus=93 node=1 flags=0x1 nice=0 stuck for 32s! [...] kernel: pool 74: cpus=37 node=0 flags=0x1 nice=0 hung=32s workers=2 manager: 2146 kernel: pwq 498: cpus=249 node=1 flags=0x1 nice=0 active=4/256 refcnt=5 kernel: in-flight: 1917:fill_page_cache_func kernel: pending: dbs_work_handler, free_work, kfree_rcu_monitor Originally, we thought that the root cause of this lockup was several retries with direct reclaim, but this is not yet confirmed. Furthermore, we have seen similar lockups without any heavy memory pressure. This suggests that there are other factors contributing to these lockups. However, it is not really clear that endless retries are desireable. So let's make the fill_page_cache_func() function back off after allocation failure.

[PATCH AUTOSEL 4.19 1/6] ACPI: video: Add Toshiba Satellite/Portege Z830 quirk

by Sasha Levin

From: Arvid Norlander <lkml(a)vorpal.se> [ Upstream commit 574160b8548deff8b80b174f03201e94ab8431e2 ] Toshiba Satellite Z830 needs the quirk video_disable_backlight_sysfs_if for proper backlight control after suspend/resume cycles. Toshiba Portege Z830 is simply the same laptop rebranded for certain markets (I looked through the manual to other language sections to confirm this) and thus also needs this quirk.

[PATCH net 3/4] can: kvaser_usb_leaf: Fix TX queue out of sync after restart

by Marc Kleine-Budde

From: Anssi Hannula <anssi.hannula(a)bitwise.fi> The TX queue seems to be implicitly flushed by the hardware during bus-off or bus-off recovery, but the driver does not reset the TX bookkeeping. Despite not resetting TX bookkeeping the driver still re-enables TX queue unconditionally, leading to "cannot find free context" / NETDEV_TX_BUSY errors if the TX queue was full at bus-off time. Fix that by resetting TX bookkeeping on CAN restart. Tested with 0bfd:0124 Kvaser Mini PCI Express 2xHS FW 4.18.778.

[PATCH net 2/4] can: kvaser_usb: Fix use of uninitialized completion

by Marc Kleine-Budde

From: Anssi Hannula <anssi.hannula(a)bitwise.fi> flush_comp is initialized when CMD_FLUSH_QUEUE is sent to the device and completed when the device sends CMD_FLUSH_QUEUE_RESP. This causes completion of uninitialized completion if the device sends CMD_FLUSH_QUEUE_RESP before CMD_FLUSH_QUEUE is ever sent (e.g. as a response to a flush by a previously bound driver, or a misbehaving device). Fix that by initializing flush_comp in kvaser_usb_init_one() like the other completions. This issue is only triggerable after RX URBs have been set up, i.e. the interface has been opened at least once.
