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 --- The following changes since commit 03c765b0e3b4cb5063276b086c76f7a612856a9a:
