Currently, if an AIO/DIO/O_SYNC write is issued, generic_write_sync is
called after the submission of the I/O instead of after the completion.
This can result in flushing the disk cache before the actual write even
gets there!  This patch set attempts to fix that for xfs and ext4.
Comments would be greatly appreciated.

Cheers,
Jeff
