Public bug reported:
[Impact]
test-execute autotest is failing in focal with kernel 5.15. This is
because the following kernel commit changed the ABI for ioprio:
e70344c05995 ("block: fix default IO priority handling")
Previously setting IOPRIO_CLASS_NONE for a process would report
IOPRIO_CLASS_NONE back. But starting with 5.15 it reports
IOPRIO_CLASS_BE instead.
[Test case]
Run systemd autopkgtest and check for the test-execute result.
[Fix]
Change test/test-execute/exec-ioschedulingclass-none.service to
recognize both "none" and "best-effort" as valid returned strings from
ionice.
This change is already available in jammy and above.
[Regression potential]
We may see regressions in systemd autopkgtest, we won't introduce any
potential regressions in systemd itself, because this is only affecting
the specific unit test.
