Subject: [GIT PULL] pidfd fixes

Hi Linus,

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.

The following changes since commit 609488bc979f99f805f34e9a32c1e3b71179d10b:

  Linux 5.3-rc2 (2019-07-28 12:47:02 -0700)
