This patchset includes three patches: one to add a new LSM hook for
the IORING_OP_URING_CMD operation, one to add the SELinux
implementation for the new hook, and one to enable
IORING_OP_URING_CMD for /dev/null.  The last patch, the /dev/null
support, is obviously not critical but it makes testing so much
easier and I believe is in keeping with the general motivation behind
/dev/null.

Luis' patch has already been vetted by Jens and the io_uring folks,
so the only new bits are the SELinux implementation and the trivial
/dev/null implementation of IORING_OP_URING_CMD.  Assuming no one
has any objections over the next few days, I'll plan on sending this
up to Linus during the v6.0-rcX cycle.

I believe Casey is also currently working on Smack support for the
IORING_OP_URING_CMD hook, and as soon as he is ready I can add it
to this patchset (or Casey can send it up himself).

Forgive me, I spaced and hit send on this patchset posting a *second*
too soon and didn't cancel it in time so the cover letter leaked out.
A proper patchset posting will be coming in just another minute ...
