Test that a direct IO write works against raid5/6 filesystems and that after the write operation we are able to read back the correct data and scrub operations don't find any errors. This test is motivated by a regression introduced in the merge window for the 4.13 linux kernel, which was undetected by the current set of test cases. The issue is fixed by the following patch: "Btrfs: fix write corruption due to bio cloning on raid5/6" Signed-off-by: Filipe Manana <fdmanana@suse.com> Reviewed-by: Liu Bo <bo.li.liu@oracle.com> Signed-off-by: Eryu Guan <eguan@redhat.com>
