Subject: [PATCH v9 0/4] xfs: Remove wrappers for some semaphores
Date: Tue,  6 Oct 2020 21:15:37 +0200	[thread overview]
Message-ID: <20201006191541.115364-1-preichl@redhat.com> (raw)

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).

Changes in version 9:
*Fixed white space in patch 'xfs: Refactor xfs_isilocked()'
*Updated code comments as suggested by djwong (thanks!) in patch: 'xfs: replace mrlock_t with rw_semaphores'

  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
