| H A D | fsync.c | d755fb38 Fri Jul 11 18:27:31 CDT 2008 Eric Sandeen <sandeen@redhat.com> ext4: call blkdev_issue_flush on fsync
To ensure that bits are truly on-disk after an fsync,
we should call blkdev_issue_flush if barriers are supported.
Inspired by an old thread on barriers, by reiserfs & xfs
which do the same, and by a patch SuSE ships with their kernel
