I have no interest in a takeover in the 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. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
