Subject: [LSF/MM/BPF TOPIC] Enabling change notification for network and
 cluster fs

Currently only local events can be waited on with the current notify
kernel API since the requests to wait on these events is not passed to
the filesystem.   Especially for network and cluster filesystems it is
important that they be told that applications want to be notified of
these file or directory change events.

A few years ago, discussions began on the changes needed to enable
support for this.   Would be timely to finish those discussions, as
waiting on file and directory change events to network mounts is very
common for other OS, and would be valuable for Linux to fix.
