2023-10-06quota: Fix slow quotaoffJan Kara3-29/+43
Eric has reported that commit dabc8b207566 ("quota: fix dqput() to follow the guarantees dquot_srcu should provide") heavily increases runtime of generic/270 xfstest for ext4 in nojournal mode. The reason for this is that ext4 in nojournal mode leaves dquots dirty until the last dqput() and thus the cleanup done in quota_release_workfn() has to write them all. Due to the way quota_release_workfn() is written this results in synchronize_srcu() call for each dirty dquot which makes the dquot cleanup when turning quotas off extremely slow. To be able to avoid synchronize_srcu() for each dirty dquot we need to rework how we track dquots to be cleaned up. Instead of keeping the last dquot reference while it is on releasing_dquots list, we drop it right away and mark the dquot with new DQ_RELEASING_B bit instead. This way we can we can remove dquot from releasing_dquots list when new reference to it is acquired and thus there's no need to call synchronize_srcu() each time we drop dq_list_lock.

2023-10-06HID: i2c-hid: fix handling of unpopulated devicesJohan Hovold1-63/+81
A recent commit reordered probe so that the interrupt line is now requested before making sure that the device exists. This breaks machines like the Lenovo ThinkPad X13s which rely on the HID driver to probe second-source devices and only register the variant that is actually populated. Specifically, the interrupt line may now already be (temporarily) claimed when doing asynchronous probing of the touchpad: genirq: Flags mismatch irq 191. 00082008 (hid-over-i2c) vs. 00082008 (hid-over-i2c) i2c_hid_of 21-0015: Could not register for hid-over-i2c interrupt, irq = 191, ret = -16 i2c_hid_of: probe of 21-0015 failed with error -16 Fix this by restoring the old behaviour of first making sure the device exists before requesting the interrupt line. Note that something like this should probably be implemented also for "panel followers", whose actual probe is currently effectively deferred until the DRM panel is probed (e.g. by powering down the device after making sure it exists and only then register it as a follower).

2023-10-05cpufreq: schedutil: Update next_freq when cpufreq_limits changeXuewen Yan1-1/+2
When cpufreq's policy is 'single', there is a scenario that will cause sg_policy's next_freq to be unable to update. When the CPU's util is always max, the cpufreq will be max, and then if we change the policy's scaling_max_freq to be a lower freq, indeed, the sg_policy's next_freq need change to be the lower freq, however, because the cpu_is_busy, the next_freq would keep the max_freq. For example: The cpu7 is a single CPU: unisoc:/sys/devices/system/cpu/cpufreq/policy7 # while true;do done& [1] 4737 unisoc:/sys/devices/system/cpu/cpufreq/policy7 # taskset -p 80 4737 pid 4737's current affinity mask: ff pid 4737's new affinity mask: 80 unisoc:/sys/devices/system/cpu/cpufreq/policy7 # cat scaling_max_freq 2301000 unisoc:/sys/devices/system/cpu/cpufreq/policy7 # cat scaling_cur_freq 2301000 unisoc:/sys/devices/system/cpu/cpufreq/policy7 # echo 2171000 > scaling_max_freq unisoc:/sys/devices/system/cpu/cpufreq/policy7 # cat scaling_max_freq 2171000 At this time, the sg_policy's next_freq would stay at 2301000, which is wrong. To fix this, add a check for the ->need_freq_update flag.

Note that unlike most of Al's series, these two patches are not about racing with ->kill_sb() and they are also very recent regressions from v6.5, so I think it's worth getting them into v6.5.y. There is also a fix for an RCU pathwalk race with ->kill_sb(), which may have been solved in vfs generic code as you suggested, but it also rids overlayfs from a nasty hack, so I think it's worth anyway.

2023-10-05mptcp: fix delegated action racesPaolo Abeni3-39/+34
The delegated action infrastructure is prone to the following race: different CPUs can try to schedule different delegated actions on the same subflow at the same time. Each of them will check different bits via mptcp_subflow_delegate(), and will try to schedule the action on the related per-cpu napi instance. Depending on the timing, both can observe an empty delegated list node, causing the same entry to be added simultaneously on two different lists. The root cause is that the delegated actions infra does not provide a single synchronization point. Address the issue reserving an additional bit to mark the subflow as scheduled for delegation. Acquiring such bit guarantee the caller to own the delegated list node, and being able to safely schedule the subflow. Clear such bit only when the subflow scheduling is completed, ensuring proper barrier in place. Additionally swap the meaning of the delegated_action bitmask, to allow the usage of the existing helper to set multiple bit at once.

2023-10-05net: ethernet: mediatek: disable irq before schedule napiChristian Marangi1-2/+2
While searching for possible refactor of napi_schedule_prep and __napi_schedule it was notice that the mtk eth driver disable the interrupt for rx and tx AFTER napi is scheduled. While this is a very hard to repro case it might happen to have situation where the interrupt is disabled and never enabled again as the napi completes and the interrupt is enabled before. This is caused by the fact that a napi driven by interrupt expect a logic with: 1. interrupt received. napi prepared -> interrupt disabled -> napi scheduled 2. napi triggered. ring cleared -> interrupt enabled -> wait for new interrupt To prevent this case, disable the interrupt BEFORE the napi is scheduled.

2023-10-05HID: intel-ish-hid: ipc: Disable and reenable ACPI GPE bitSrinivas Pandruvada1-0/+8
The EHL (Elkhart Lake) based platforms provide a OOB (Out of band) service, which allows to wakup device when the system is in S5 (Soft-Off state). This OOB service can be enabled/disabled from BIOS settings. When enabled, the ISH device gets PME wake capability. To enable PME wakeup, driver also needs to enable ACPI GPE bit. On resume, BIOS will clear the wakeup bit. So driver need to re-enable it in resume function to keep the next wakeup capability. But this BIOS clearing of wakeup bit doesn't decrement internal OS GPE reference count, so this reenabling on every resume will cause reference count to overflow. So first disable and reenable ACPI GPE bit using acpi_disable_gpe().

When suspending the computer, a Switch Pro Controller connected via USB will lose its internal status. However, because the USB connection was technically never lost, when resuming the computer, the driver will attempt to communicate with the controller as if nothing happened (and fail). Because of this, the user was forced to manually disconnect the controller (or to press the sync button on the controller to power it off), so that it can be re-initialized. With this patch, the controller will be automatically re-initialized after resuming from suspend.
