Audit fixes for v4.11 (#1)

[Paul Moore]

Hi Linus,

We've got an audit fix, and unfortunately it is two things I don't
like: big and based on a -rcX tag.  The size of the patch is
(hopefully) explained well in the patch description, the -rcX base is
to get access to code not present in the v4.11 pull request
(audit/next is still based off v4.8; I'll be updating soon).  While
I'm not excited that we need to be sending you something this large
during the -rcX phase, it does fix some very real, and very tangled,
problems relating to locking, backlog queues, and the audit daemon
connection.

This code has passed our testsuite without problem and it has held up
to my ad-hoc stress tests (arguably better than the existing code),
please consider pulling this as fix for the next v4.11-rcX tag.

Thanks,
-Paul
