[GIT PULL] notification tree - numerous inotify fixes

[Eric Paris]

Linus please consider pulling from the notification tree.  They are all
bug fixes in either inotify or fsnotify which were introduced with the
fsnotify conversion.  We've got a DoS, OOM, deadlock, functionality
regression, and all sorts of fun.....
