Hi Gautham,

Thanks for posting this. I believe this is the same version of preempt RCU
as we have in the RT patch. It seems to be very stable. I ran the RT patch
version of the RCU Preempt (just the Preempt RCU patches without RT on
latest git) on a 64way box and the results seems just as good (if not
slightly better) than classic RCU!  I'll rerun this patch series on that
box and post the results.

>From what I'm seening with this, is that it is ready for mainline. These
patches should probably go into -mm and be ready for 2.6.25.  If Andrew
wants to wait for my results, I'll run them tonight.

Thanks Gautham, Paul and Dipankar for all this great work!
