Previously discussed here: https://www.redhat.com/archives/libguestfs/2019-July/msg00213.html It turns out that deferring callbacks is a PITA. (It would be a bit easier if C has closures.) However by rewriting the example we can avoid the need to use the cookie at all and make it run a bit more efficiently, so let's do that instead. Rich.

...bsd 9 based. Then I have noticed that the link is missing and the free ports were missing from ifconfig. Checking the dmesg revealed the problem. ixN: Hardware Initialization Failure SPF+ module missing *narf* It's the same bug as this PR http://www.mail-archive.com/freebsd-bugs@freebsd.org/msg00213.html Thanks and have a good day, -dennis

We previously needed nbd_add_close_callback to do cleanup from language bindings. However now we have closure lifetimes this is no longer needed and can be removed.

I think I've addressed everything that was raised in review. Some of the highlights: - Callbacks should be freed reliably along all exit paths. - There's a simple test of closure lifetimes. - I've tried to use VALID|FREE in all the places where I'm confident that it's safe and correct to do. There may be more places. Note this is an optimization and shouldn't

v1 was here: https://www.redhat.com/archives/libguestfs/2019-July/thread.html#00231 The changes address everything that Eric picked up in his review of the first two patches. I have also added two more patches (4 and 5) which respectively fix docs and change int status -> unsigned status, as discussed. Passes make, check, check-valgrind. Rich.
