/* v13 */
- Make sure that idmapped-mount tests are skipped on unsupported
  filesystems.

/* v12 */
- Main change is a fix to the io_uring tests. io_uring_wait_cqe()
  doesn't set errno, it returns a negative errno.
- Make sure we also run without error when libcap isn't available (That
  was always the goal but the logic missed a few new tests.)

/* v11 */
Reworked according to Amir's comments.

/* v10 */
Reworked according to Eryu's comments.

/* v9 */
Rebased onto current master.

Thanks!
Christian
