These patches are also available at. https://github.com/rhvgoyal/linux/commits/dax-zero-range-v5 Changes since V4: - Rebased on top of 5.6-rc2 - Added a separate patch so that pmem_clear_poison() accepts arbitrary offset and len and aligns these as needed. This takes away the burden of aligning from callers.
