[GIT PULL] notification bug fixes

[Eric Paris]

The notable fixes in this pull request include a potential deadlock when
fanotify listeners exit, an unpriv user kernel memory DoS in inotify,
and an API (although not ABI) change in fanotify's userspace message to
support expansion in the next release.
