The regression is introduced to btrfs in linux v4.4 and it refuses to create new files after log replay by returning -EEXIST. Although the problem is on btrfs only, there is no btrfs stuff in terms of test, so this makes it generic. The kernel fix is Btrfs: fix unexpected -EEXIST when creating new inode [Eryu: add _require_metadata_journaling rule and 'log' 'metadata' group] Reviewed-by: Filipe Manana <fdmanana@suse.com> Signed-off-by: Liu Bo <bo.li.liu@oracle.com> Signed-off-by: Eryu Guan <guaneryu@gmail.com>
