Re: [PATCH libnbd 1/7] api: Add semi-private function for freeing persistent data.
...ut_of_memory ();
*buf_user_data = bufv;
caml_register_generational_global_root (buf_user_data);
struct nbd_buffer *buf_buf = NBD_buffer_val (bufv);
const void *buf = buf_buf->data;

free_root, buf_user_data) == -1)
caml_raise_out_of_memory ();
Notice that the free_root function needs the pointer to the GC root,
but you can't get to that from the buffer pointer.
A similar problem will exist in Python, but I've not got around to
writing that code yet.

[PATCH libnbd 0/7] Add free callbacks and remove valid_flag.
As proposed here:
https://www.redhat.com/archives/libguestfs/2019-August/msg00130.html
I didn't actually read Eric's replies to that yet because I've been
concentrating on writing these patches all day. Anyway here they are
and I'll look at what Eric said about the proposal next.

But still, can't we create a single C struct that tracks both the buffer
and the GC root, and...
