Subject: [RFC PATCH 0/5] Overhaul the audit filename handling

There have been some patches added to v3.19-rcX to fix various
problems in the way audit handles filenames but they have been hacks
on top of hacks, not really something we want long term.  This
patchset reworks the way audit handles filenames, removing a lot of
nasty hacks added recently, and fixing a few bugs that still remain.

Most significant to folks outside of audit, patch 5/5 does away with
the nasty getname()/putname() kludge in favor of a less ugly reference
count approach.

Comments and feedback are welcome.  If nothing ugly pops up on review
I'll see if Linus is interested in taking this for the next v3.19-rcX
release, otherwise I'll toss it into linux-next for v3.20.

-Paul
