Hi,
I haven't had time to debug this issue myself, but I did suspect that
there was some corner case where the biglock should be unlocked when
calling code outside the kernel extension, so this fix probably makes sense.
However, fuse_msleep is used in various places... and really, when
msleep is called, it should be generally considered that code 'exits'
the kernel extension and the biglock doesn't need to be held during this
time.
So I think it might be more appropriate to do something in 'fuse_msleep'
itself to cover all possible cases.
Regards,
- Erik

Thanks Jeff for the link. It looks very promising! I did some
preliminary tests and it seems to fix Dan's issue. So far no deadlock.
Anatol, if you are reading this: Nice work!
Regards,
Benjamin

It now appears Anatol has a fix in place on his kext branch:
https://github.com/fuse4x/kext/commit/1babb2b848eb75047267bd998ec417fb65c9de85
I haven't tested this myself, but I'm interested to see if it fixes
Dan's repro case
