Subject[PATCH v3 0/2] Fixes for fscache volume operations
Date
From: Hou Tao <houtao1@huawei.com>

Hi,

The patchset includes two fixes for fscache volume operations: patch 1
fixes the hang problem during volume acquisition when the volume
acquisition process waits for the freeing of relinquished volume, patch
2 adds the missing memory barrier in fscache_create_volume_work() and it
is spotted through code review when checking whether or not these is
missing smp_mb() before invoking wake_up_bit().

Comments are always welcome.

Chang Log:
v3:
* Use clear_and_wake_up_bit() helper (Suggested by Jingbo Xu)
* Tidy up commit message and add Reviewed-by tag

v2: https://listman.redhat.com/archives/linux-cachefs/2022-December/007402.html
* rebased on v6.1-rc1
* Patch 1: use wait_on_bit() instead (Suggested by David)
* Patch 2: add the missing smp_mb() in fscache_create_volume_work()

v1: https://listman.redhat.com/archives/linux-cachefs/2022-December/007384.html


Hou Tao (2):
fscache: Use wait_on_bit() to wait for the freeing of relinquished
volume
fscache: Use clear_and_wake_up_bit() in fscache_create_volume_work()
