Ah great, so you're maintaining those! Just a moment before seeing
this I post, I uploaded them too at this URL:
http://www.kernel.org/pub/linux/kernel/people/andrea/patches/v2.6/2.6.26-rc7/mmu-notifier-v18/
Since you're taking care of this yourself should I feel free to remove
those from my patchset right?
With a VM hat I don't think those lock changes should be
unconditional... especially for the anon-vma case where the common case
are small critical section. But then with a KVM hat those won't make
the slightest difference to my current interesting workload, so it's
truly not my concern if those goes in as-is.
