[GIT PULL] Audit patches for v4.10

[GIT PULL] Audit patches for v4.10

[Paul Moore]

Hi Linus,

After the small number of patches for v4.9, we've got a much bigger pile for 
v4.10.

The bulk of these patches involve a rework of the audit backlog queue to 
enable us to move the netlink multicasting out of the task/thread that 
generates the audit record and into the kernel thread that emits the record 
(just like we do for the audit unicast to auditd).  While we were playing 
with the backlog queue(s) we fixed a number of other little problems with 
the code, and from all the testing so far things look to be in much better 
shape now.  Doing this also allowed us to re-enable disabling IRQs for some 
netns operations ("netns: avoid disabling irq for netns id").  The remaining 
patches fix some small problems that are well documented in the commit 
descriptions, as well as adding session ID filtering support.

You will likely hit two merge conflicts, one in net/core/net_namespace.c and 
one in include/uapi/linux/audit.h, both are easily resolved so I won't 
bother you with that here.  If you have questions, you know how to find me.

Thanks,
-Paul
