Test file A fsync after moving one other unrelated file B between directories and fsyncing B's old parent directory before fsyncing the file A. Check that after a crash all the file A data we fsynced is available. This test is motivated by an issue discovered in btrfs which caused the file data to be lost (despite fsync returning success to user space). That btrfs bug is fixed by the following linux kernel patch: Btrfs: fix data loss in the fast fsync path Signed-off-by: Filipe Manana <fdmanana@suse.com> Reviewed-by: Lukas Czerner <lczerner@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>
