filesystem notification: create fs/notify to contain all fs notification
Eric Paris [Wed, 17 Dec 2008 18:59:41 +0000 (13:59 -0500)]
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 to make both current fs/
and future notification tidier.
