If we heave the LSM stuff overboard, there's one thing that *will* need
addressing - what to do with kernel support of Posix-y capabilities. Currently
some of the heavy lifting is done by security/commoncap.c.

Frankly, that's *another* thing that we need to either *fix* so it works right,
or rip out of the kernel entirely. As far as I know, there's no in-tree way
to make /usr/bin/ping be set-CAP_NET_RAW and have it DTRT.
