Shutemov" <kirill.shutemov@...ux.intel.com>, linux-nvdimm@...ts.01.org, Matthew Wilcox <matthew.r.wilcox@...el.com> Subject: [PATCH v4 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 v3: - reduced the revert of 46c043ede471 in patch 1 so that we still drop the mapping->i_mmap_rwsem before calling unmap_mapping_range(). This prevents the deadlock in the __dax_pmd_fault() path so there is no longer a need to temporarily disable DAX PMD faults.
