[PATCH 1/3] filesystem notification: create fs/notify to contain allfs notification

From: Eric Paris
Date: Mon Dec 15 2008 - 11:44:38 EST

Creating a generic filesystem notification interface, fsnotify, which will be
used by inotify, dnotify, and eventually fanotify is really starting to
clutter the fs directory. This patch simply moves inotify and dnotify into
fs/notify/inotify and fs/notify/dnotify respectively.
