[GIT PULL] LSM fixes for v6.0 (#1)

[Paul Moore]

Linus,

Four patches to add SELinux and Smack controls to the io_uring
IORING_OP_URING_CMD.  Three of these patches are necessary as without
them the IORING_OP_URING_CMD remains outside the purview of the LSMs
(Luis' LSM patch, Casey's Smack patch, and my SELinux patch).  These
patches have been discussed at length with the io_uring folks, and
Jens has given his thumbs-up on the relevant patches (see the commit
descriptions).  There is one patch that is not strictly necessary, but
it makes testing much easier and is very trivial: the /dev/null
IORING_OP_URING_CMD patch.  If you have a problem accepting the
/dev/null patch in a rcX release, let me know and I'll remove it.

As of earlier today the tag merged cleanly with your tree, so there
should be no surprises.  Please merge for v6.0.

-Paul
