From: Hou Tao <houtao1@xxxxxxxxxx> 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: v2: * 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: Add the missing smp_mb__after_atomic() before wake_up_bit() fs/fscache/volume.c | 17 ++++++++++++++--- 1 file changed, 14 insertions(+), 3 deletions(-) -- 2.29.2 -- Linux-cachefs mailing list Linux-cachefs@xxxxxxxxxx https://listman.redhat.com/mailman/listinfo/linux-cachefs
