Merge tag 'dax-and-nvdimm-fixes-v6.0-final' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm

Pull NVDIMM and DAX fixes from Dan Williams:
 "A recently discovered one-line fix for devdax that further addresses a
  v5.5 regression, and (a bit embarrassing) a small batch of fixes that
  have been sitting in my fixes tree for weeks.

  The older fixes have soaked in linux-next during that time and address
  an fsdax infinite loop and some other minor fixups.

   - Fix a infinite loop bug in fsdax

   - Fix memory-type detection for devdax (EINJ regression)

   - Small cleanups"
