[GIT PULL] notification fixes

[Eric Paris]

Mostly bug fixes found when testing the fanotify vfsmounts.

The most serious bug (and only one affecting inotify and dnotify rather
than requiring fanotify to break something) was actually fixed
accidentally in "fsnotify: fix ignored mask handling between inode and
vfsmount marks".  It was possible for inotify to get events it didn't
request or even events with a 0 mask.

The only other interesting note is that "fanotify: resize pid and
reorder structure" will require users to rebuild any fanotify listeners.
It's an ABI change, not an API change, which should help us improve
performance in the future on strict alignment platforms (without
breaking ABI)
