I do not want to take null key flushing away although I got the
reasoning given the small amount of time is saved (maybe 25-50 ms
in my QEMU setup if I recall correctly) but it would make sense to
squash it auth session patch.

I'll also check 1/2 and 2/2 if I'm doing too much in them. Not
adding any tags to v6 and it really makes sense to develop 
benchmarks and not rush with the new version now that I got
also your feedback, since it is past rc1 timeline.

Good target rcX would be around rc3.
