Will definitely do this week. Thanks; I appreciate the feedback you've provided so far. > Please also note that there will be merge conflicts with atomic open patches > from Dharmendra/me. Although probably not too difficult to resolve. Sure. I'm happy to reparent, resolve those conflicts, re-test, and send another revision when we're ready. I suspect there are going to be additional changes requested on the v2. With that in mind, I'll hold off for the moment unless it is going to cause headaches for you. For the atomic-open-revalidate changes: should I be working from what's on the list? This is the most recent patchset I see: https://lore.kernel.org/linux-fsdevel/20230920173445.3943581-1-bschubert@xxxxxxx/ I found a 6.5 relative tree of yours on GitHub by following the libfuse pull request, but nothing that seemed in sync with fuse/for-next. Thanks, -K
