It is difficult to know where to send a patch for every subsystem. I've
been using the get_maintainer.pl script, so perhaps the info in
MAINTAINERS is stale ? I'm open to suggestions.

$: scripts/get_maintainer.pl -f security/selinux/ss/services.c

James Morris <james.l.morris@xxxxxxxxxx> (supporter:SELINUX SECURITY...)
Eric Paris <eparis@xxxxxxxxxxxxxx> (supporter:SELINUX SECURITY...)
linux-security-module@xxxxxxxxxxxxxxx (open list:SECURITY SUBSYSTEM)
linux-kernel@xxxxxxxxxxxxxxx (open list)
