Subject: [PATCH v2 0/2] Revert locking changes in DAX for v4.3

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.

Ross Zwisler (2):
  Revert "mm: take i_mmap_lock in unmap_mapping_range() for DAX"
  Revert "dax: fix race between simultaneous faults"
