Thanks for the work, I was on vacation and travelling after my initial RCU
conversion so I got a little behind with these conversions, my idea was quite
different :-)
Anyway, I'd also appreciate some benchmarks, also some more information on what
type of testing did you run ?
I've given some preliminary comments to the patches, I'll have to think more
about them in this form.

Cheers,
 Nik
