Subject: [PATCH v2 0/2] Revert locking changes in DAX for v4.3
Date: Fri, 2 Oct 2015 18:01:32 -0600 [thread overview]
Message-ID: <1443830494-8748-1-git-send-email-ross.zwisler@linux.intel.com> (raw)
This series reverts some recent changes to the locking scheme in DAX introduced
by these two commits:
commit 843172978bb9 ("dax: fix race between simultaneous faults")
commit 46c043ede471 ("mm: take i_mmap_lock in unmap_mapping_range() for DAX")
Changes from v1:
- Squashed patches 1 and 2 from the first series into a single patch to avoid
adding another spot in the git history where we could end up referencing an
uninitialized pointer.
