Hello,
This version of the series is unchanged from v2 except for the last patch which is completely new, and is provided by Mike Rapoport.
Original series description:
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 v2:
- Added Mike Rapoport's Reviewed-by's and Acked-by's to patches 1-3. - Replaced patch 4/4 by the one provided by Mike Rapoport.
Changes since v1:
- Patch "userfaultfd: selftest: Skip test if userfaultfd() syscall not supported" - New patch, suggested by Mike 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.
Mike Rapoport (1): userfaultfd: selftest: make supported range ioctl verification more robust
Thiago Jung Bauermann (3): userfaultfd: selftest: Fix checking of userfaultfd_open() result userfaultfd: selftest: Skip test if userfaultfd() syscall not supported userfaultfd: selftest: Skip test if a feature isn't supported
