Merge branch 'upstream' of git://git.infradead.org/users/pcmoore/audit
Pull audit updates from Paul Moore:
"Seven audit patches for 4.4, but really only one of any significant
value, the remainder are trivial cleanups that are described well
enough in the patch descriptions.
The one significant patch is an attempt to make communication between
the kernel's audit subsystem and the userspace audit daemon a bit more
robust by retrying on certain transient error conditions. All in all,
it's a pretty small set of patches this time around with just fixes
and cleanups"
