Message-ID: <1444258729-21974-1-git-send-email-ross.zwisler@linux.intel.com> (raw)

This was previously "Revert locking changes in DAX for v4.3".

Undo 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 v4:
 - Collapsed two revert commits into a single fix commit.  No code changes were
   made.
