[PATCH v4 0/8] Add LSM access controls and auditing to io_uring

[Paul Moore]

A quick update to the v3 patchset with a small change to the audit
record format (remove the audit login ID on io_uring records) and
a subject line fix on the Smack patch.  I also caught a few minor
things in the code comments and fixed those up.  All told, nothing
significant but I really dislike merging patches that haven't hit
the list so here ya go ...

As a reminder, I'm planning to merge these in the selinux/next tree
later this week and it would be *really* nice to get some ACKs from
the io_uring folks; this patchset is implementing the ideas we all
agreed to back in the v1 patchset so there shouldn't be anything
surprising in here.

For reference the v3 patchset can be found here:
