Curiously, why minimum 1 range is not adequate? In which case minimum 2

Frankly speaking, right now I don't remember. I have vague memories
of concluding in the past that 1 range is not sufficient. But if you
like dive deeper, and try with one range and see if you can introduce
deadlock.
Alright, thanks.
Out of interest, how are you testing this at all? A patch from
Dharmendra had been merged last week into libfuse to let it know about
flags2, as we need that for our patches. But we didn't update the FLAGS
yet to add in DAX on the libfuse side.
Is this used by virtio fs? Or is there another libfuse out there that
should know about these flags (I think glusterfs has its own, but
probably not using dax?).
Also, testing is always good, although I don't see how Jeffs patch would
be able break anything here.
Thanks,
Bernd
