Ok if you want me to do this, I definitely prefer the core to go in
now. It's so much easier to concentrate on two problems at different
times then to attack both problems at the same time given they're
mostly completely orthogonal problems. Given we already solved one
problem, I'd like to close it before concentrating on the second
problem. I already told you it was my interest to support XPMEM
too. For example it was me to notice we couldn't possibly remove
can_sleep parameter from invalidate_range without altering the locking
as vmas were unstable outside of one of the three core vm locks. That
finding resulted in much bigger patches than we hoped (like Andrew
previously sort of predicted) and you did all great work to develop
those. From my part, once the converged part is in, it'll be a lot
easier to fully concentrate on the rest. My main focus right now is to
produce a mmu-notifier-core that is entirely bug free for .26.
