Hi,

The recent 2.6.26 release didn't say anything about mmu-notifiers. My
impression was that it will be going to be included
in that release. Where can I download and try it out, what host/guest
kernel should I use and are there any current issues/bugs ?

Thanks
arn

Sorry for the late reply I was on vacation last week.

Yes, it should be included any moment in 2.6.27-rc, Andrew should be
taking care of it, crossing fingers here...

You can use 2.6.25/6 plus these three patches applied in order:

       http://kernel.org/pub/linux/kernel/people/andrea/patches/v2.6/2.6.26-rc7/mmu-notifier-v18/list_del_init_rcu
       http://kernel.org/pub/linux/kernel/people/andrea/patches/v2.6/2.6.26-rc7/mmu-notifier-v18/mm_take_all_locks
       http://kernel.org/pub/linux/kernel/people/andrea/patches/v2.6/2.6.26-rc7/mmu-notifier-v18/mmu-notifier-core

I posted the latest kvm-mmu-notifier patch on this list a few days
before your question, that has to be applied to kvm.git. That's all.

With the last patch I posted there are two issues pointed out by
Marcelo, with largepages and with aliases but you won't risk to
notice, I'm correcting those as I write this.
