[GIT PULL] fscache: Miscellaneous fixes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
