Re: [PATCH 2/4] mm: Send a single IPI to TLB flush multiple pages when unmapping

I did a quick read and it looks good to me.

It's a bit ugly to bloat current with the ubc pointer,
but i guess there's no good way around that.

Also not nice to use GFP_ATOMIC for the allocation,
but again there's no way around it and it will
eventually recover if it fails. There may be
a slightly better GFP flag for this situation that
doesn't dip into the interrupt pools?
