ext4 should hold i_mutex when truncating orhpan inodes, or a WARNING would be triggered. This commit fixed this issue. 721e3eb ext4: lock i_mutex when truncating orphan inodes Though it's an ext4 specific issue, there's no harm to test on ext2/3 too, as debugfs is used to set orphan inode list. This test is based on a script from Lukas Czerner. Signed-off-by: Eryu Guan <eguan@redhat.com> Acked-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>
