Subject: [52/80] inotify: send IN_UNMOUNT events

2.6.35-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Eric Paris <eparis@...hat.com>

commit 611da04f7a31b2208e838be55a42c7a1310ae321 upstream.

Since the .31 or so notify rewrite inotify has not sent events about
inodes which are unmounted.  This patch restores those events.
