[PATCH v8 0/4] xfs: Remove wrappers for some semaphores

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

 



Remove some wrappers that we have in XFS around the read-write semaphore
locks.

The goal of this cleanup is to remove mrlock_t structure and its mr*()
wrapper functions and replace it with native rw_semaphore type and its
native calls.

Changes in version 8:
Patchset was rebased so it applies cleanly.

The patch 'xfs: replace mrlock_t with rw_semaphores' contains change in
xfs_btree.c which transfers ownership of lock so lockdep won't assert
(This was reported by Darrick and proposed change fixes this issue).

Pavel Reichl (4):
  xfs: Refactor xfs_isilocked()
  xfs: clean up whitespace in xfs_isilocked() calls
  xfs: xfs_isilocked() can only check a single lock type
  xfs: replace mrlock_t with rw_semaphores
