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"
