#     
#     Pull iomap updates from Darrick Wong:
#      "There's not a lot of new stuff going on here -- a little bit of code
#       refactoring to make iomap workable with btrfs' fsync locking model,
#       cleanups in preparation for adding THP support for filesystems, and
#       fixing a data corruption issue for blocksize < pagesize filesystems.
#     
#       Summary:
#     
#        - Don't WARN_ON weird states that unprivileged users can create.
#     
#        - Don't invalidate page cache when direct writes want to fall back to
#          buffered.
#     
#        - Fix some problems when readahead ios fail.
#     
#        - Fix a problem where inline data pages weren't getting flushed
#          during an unshare operation.
#     
#        - Rework iomap to support arbitrarily many blocks per page in
#          preparation to support THP for the page cache.
#     
#        - Fix a bug in the blocksize < pagesize buffered io path where we
#          could fail to initialize the many-blocks-per-page uptodate bitmap
#          correctly when the backing page is actually up to date. This could
#          cause us to forget to write out dirty pages.
#     
#        - Split out the generic_write_sync at the end of the directio write
#          path so that btrfs can drop the inode lock before sync'ing the
#          file.
#     
#        - Call inode_dio_end before trying to sync the file after a O_DSYNC
#          direct write (instead of afterwards) to match the behavior of the
#          old directio code"
