[PATCH libnbd 0/2] Use free callback to dereference NBD.Buffer.
In this patch series we use the newly introduced free callback on the completion function to dererence the OCaml NBD.Buffer. I will make the same kind of change for Python later in a separate series. The completion function is always called at the C level, even if the OCaml program didn't use the optional argument. That's because the free callback doesn't run otherwise. There is a

[PATCH 0/6] Implement OClosure.
Patches 1-4 are basically uncontroversial, straightforward refactoring and IMHO we should just push them.

[PATCH libnbd v2 00/10] Callbacks and OCaml and Python persistent buffers.
This is a combination of these two earlier series: https://www.redhat.com/archives/libguestfs/2019-August/msg00235.html https://www.redhat.com/archives/libguestfs/2019-August/msg00240.html plus changes to allow .callback = NULL / .free != NULL, and to reduce the complexity of freeing callbacks. Although it's rather long there's nothing complex here. We might consider squashing some
