Oh thanks! I see that. So you just dropped the bit spinlocked and changed
mapcount to an atomic variable, right?

That's it, yes.  It needed a little more rework than that
(see ChangeLog) but that's the main thrust.

Cool. Do you have any numbers on big SMP systems for that change? 

Sorry, no.  When I sent out the patches a second time to Andrew (didn't
copy LKML since nothing really changed from the first time in July),
I did CC Martin in the hope that he might feel the urge to run up
some numbers (or at least let him be aware of that change lest he
misinterpret numbers), but I think he was busy with other stuff.

The lab was down for rewiring, and then I forgot about it - sorry. 
Can you resend me the patch again, and I'll get off my ass and do 
something about it? ;-)
