Hi,
I recently ran into a situation where a virtiofs client began
encountering EBADF after the client / guest system had an OOM. After
reproducing the issue and debugging, the problem is caused by a
virtiofsd submount having the nodeid of its root dentry fogotten. This
occurs because it borrows the reference for this dentry from the parent
that is passed into the function.
Sorry, I didn't forget you, just didn't manage to review the 2nd version
yet. 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.
I certainly also didn't mean that you should check for merge conflicts,
it was more an annotation that it might come up - depending on the merge
order. Please don't stop to do improvements, resolving merge conflicts
shouldn't be difficult.
I'm going to add you to the atomic open patch series to keep you
updated, if you don't mind.
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.
I don't think there are conflicts with fuse-next right now, but I can
check.
Thanks,
Bernd
