[Libguestfs] [PATCH nbdkit v2 0/2] ocaml: Simplify NBDKit.set_error
v1 was here:
https://listman.redhat.com/archives/libguestfs/2021-November/msg00176.html
This version addresses all or very nearly all of the feedback.
I already posted v2 1/2, but including it again here since it is
necessary for the 2/2 to make sense.
Rich.
