tl;dr - I hope to use it in 4.18
I have been trying to get my patch for Smack that creates a
subdirectory in /proc/.../attr/ in for some time. That
patch uses the lsm field in security_hook_list. While the
Smack directory is very important for stacking, I want it
regardless as reusing the SELinux attribute files was a mistake.

Yes, we can. There would be a merge conflict should I get my way
on the Smack subdirectory.
James, I *still* want /proc/.../attr/smack regardless of the rest
of stacking. I want to start fixing the Smack user space. This is
required, by stacking, but strongly desired in any case.
