I'm not sure whether I understand correctly.

In MUSE one use case would be attaching two distinct (variable length) buffers to a
single FUSE request, in both directions.
If I read fuse_do_ioctl() correctly, it attaches always a single buffer per request
but does multiple requests.

In MUSE we cold go the same path and issue up to two requests.
One for in-band and optionally a second one for the out-of-band data.
Hmmm?

Thanks,
