Subject: [PATCH] filesystems: add two new filesystem groups
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

1. @anonymous → for file systems that aren't real file systems but
   simply the backing for sockets, pipes and other "anonymous" fds.

2. @security → for the various MAC security file systems.
