Hi Bernard,

I apologize for the late response, this was lost in my inbox for some
reason. Regardless, this looks fine to me so I'm merging it into
selinux/next; thanks for your help.

However, Ondrej made a few good suggestions about further improvements
that could be made up at the LSM layer, I think it would be nice if
you could look into that too.

Thanks again for your help.
