If you specifically don't want in-kernel LSMs, and you specifically do want an out-of-tree LSM,
there are other options. For example, you could just livepatch the security_* hooks you need, 
since you already would using an LKM-based LSM.  That would give you your
out-of-tree module and would also disable selinux on the hooks that got livepatched.
