Pull pidfd fixes from Christian Brauner:
"This makes setting the exit_state in exit_notify() consistent after
fixing the pidfd polling race pre-rc1. Related to the race fix, this
adds a WARN_ON() to do_notify_pidfd() to catch any future exit_state
races.
Last, this removes an obsolete comment from the pidfd tests"
