Subject[GIT PULL] fscache: Miscellaneous fixes
Date
Hi Linus,

Could you pull these fscache/cachefiles fixes please?

(1) 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.

(2) Not a fix per se, but neaten the code by using a helper to check for
the DROPPED state.

(3) Fix cachefiles's support for erofs to only flush requests associated
with a released control file, not all requests.

(4) Fix a race between one process invalidating an object in the cache and
another process trying to look it up.

Thanks,
David
