Merge tag 'fscache-fixes-20220708' of git://git./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.
