cgroup hooks next to the lsm hooks. So in fs/namei.c where there are security_inode_permission() hooks, there would also be cgroup_inode_permission() hooks to let the devices cgroup mediate the access. Well, in permission(), probably not in exec_permission_lite() since that's probalby not a device access :)
So far it looks like everyone likes that, so as long as you don't nack I guess that'll be the way to go.
thanks, -serge
