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 tools/testing/selftests/vm/userfaultfd.c | 113 +++++++++++++++++++------------ 1 file changed, 69 insertions(+), 44 deletions(-)
