Subject[PATCH v2 00/11] DAX fsynx/msync support
Date
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. You can grab
them here:
