This patch series adds support for fsync/msync to DAX. Patches 1 through 7 add various utilities that the DAX code will eventually need, and the DAX code itself is added by patch 8. Patches 9-11 update the three filesystems that currently support DAX, ext2, ext4 and XFS, to use the new DAX fsync/msync code. These patches build on the recent DAX locking changes from Dave Chinner, Jan Kara and myself. Dave's changes for XFS and my changes for ext2 have been merged in the v4.4 window, but Jan's are still unmerged.
