[PATCH v2 0/3] userfaultfd: selftests: cleanups and trivial fixes

[Peter Xu]

v2:
- add a-bs
- add examples for non-anon tests [Mike]
- use brackets properly for nested ifs [Mike]

Recently I wrote some uffd write-protection test for the
not-yet-published uffd-wp tree, and I picked these common patches out
first for the selftest which even suite for master.

Any feedback is welcomed.  Please have a look, thanks.

Peter Xu (3):
  userfaultfd: selftest: cleanup help messages
  userfaultfd: selftest: generalize read and poll
  userfaultfd: selftest: recycle lock threads first
