This tests creates several directories that have the same small (8) group of hashes to ensure the hash ordering of file and directories are preserved. Sample backtrace this test tries to prevent in future: [ 3856.245843] XFS (vda1): Internal error xfs_trans_cancel at line 966 of file fs/xfs/xfs_trans.c.
