Hello,
A tester ran the upstream selftest on a distro kernel and sounded the alarm when it reported failures for features which aren't included in that kernel.
This patch set improves the test behavior in that scenario.
Changes since v1:
- Patch "userfaultfd: selftest: Skip test if userfaultfd() syscall not supported" - New patch, suggested by Mke Rapoport.
- Patch "userfaultfd: selftest: Skip test if a feature isn't supported" - Try running other tests even if one (or more) of them returns KSFT_SKIP.
- Patch "userfaultfd: selftest: Cope if shmem doesn't support zeropage" - Ignore lack of UFFDIO_ZEROPAGE in userfaultfd_events_test() and userfaultfd_stress(). - Make userfaultfd_zeropage_test() return KSFT_SKIP if UFFDIO_ZEROPAGE isn't supported.
