Unless you have to respin this patchset for some other reason I
wouldn't worry about it.
I've been working my way through the patchset this week (currently on
09/11) and I expect to finish it up today. Assuming everything looks
good, I'm going to merge this into a working branch, include it in my
weekly -rc test builds, and beat on it for a couple of weeks. If all
is good I'll merge it into audit/next after the upcoming merge window.
Thanks for your patience.
