[PATCH 0/3] userfaultfd: selftest: Improve behavior with older kernels

[Thiago Jung Bauermann]

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.

Thiago Jung Bauermann (3):
  userfaultfd: selftest: Fix checking of userfaultfd_open() result
  userfaultfd: selftest: Skip test if a feature isn't supported
  userfaultfd: selftest: Report XFAIL if shmem doesn't support zeropage
