    Merge branch 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
    
    Pull DAX updates from Dan Williams:
     "The completion of Jan's DAX work for 4.10.
    
      As I mentioned in the libnvdimm-for-4.10 pull request, these are some
      final fixes for the DAX dirty-cacheline-tracking invalidation work
      that was merged through the -mm, ext4, and xfs trees in -rc1. These
      patches were prepared prior to the merge window, but we waited for
      4.10-rc1 to have a stable merge base after all the prerequisites were
      merged.
    
      Quoting Jan on the overall changes in these patches:
    
         "So I'd like all these 6 patches to go for rc2. The first three
          patches fix invalidation of exceptional DAX entries (a bug which
          is there for a long time) - without these patches data loss can
          occur on power failure even though user called fsync(2). The other
          three patches change locking of DAX faults so that ->iomap_begin()
          is called in a more relaxed locking context and we are safe to
          start a transaction there for ext4"
    
      These have received a build success notification from the kbuild
      robot, and pass the latest libnvdimm unit tests. There have not been
      any -next releases since -rc1, so they have not appeared there"
    
    * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm:
      ext4: Simplify DAX fault path
      dax: Call ->iomap_begin without entry lock during dax fault
      dax: Finish fault completely when loading holes
      dax: Avoid page invalidation races and unnecessary radix tree traversals
      mm: Invalidate DAX radix tree entries only if appropriate
      ext2: Return BH_New buffers for zeroed blocks
