Merge tag 'fscache-fixes-20220708' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
Pull fscache fixes from David Howells:
- Fix a check in fscache_wait_on_volume_collision() in which the
polarity is reversed. It should complain if a volume is still marked
acquisition-pending after 20s, but instead complains if the mark has
been cleared (ie. the condition has cleared).
Also switch an open-coded test of the ACQUIRE_PENDING volume flag to
use the helper function for consistency.
- Not a fix per se, but neaten the code by using a helper to check for
the DROPPED state.
- Fix cachefiles's support for erofs to only flush requests associated
with a released control file, not all requests.
- Fix a race between one process invalidating an object in the cache
and another process trying to look it up.
