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.
