We're not very consistent on '1.2' vs. '1.2.0' in since listings, but
that's probably worth a global cleanup closer to hard freeze.
I'll make a note of it. Or does Luiz usually do a cleanup?
No idea.
Luiz, were you planning to take a pass at cleaning up the "since"
release? If not let me know and I can submit a patch. Just let me know
which to use, '1.2' or '1.2.0'.

Is it worth providing any additional information? For example, knowing
whether the fd is O_RDONLY, O_WRONLY, or O_RDWR might be beneficial to
management apps trying to discover what fds are already present after a
reconnection, in order to decide whether to close them without having to
resort to /proc/$qemupid/fdinfo/nnn lookups. It might even be worth
marking such information optional, present only when 'removed':false.
It makes sense but I'd like to limit the new functionality at this point
so that I can get this support into QEMU 1.2. Can this be added as a
follow up patch?
I'm personally okay with the idea of adding additional output fields in
later releases, but I know that has been questioned in the past, so you
may want to get buy-in from Luiz or Anthony. I guess the other thing is
to see what libvirt would actually find useful, once I complete some
counterpart libvirt patches. If libvirt can get by without any extra
information and without needing to hack things from procfs, then it's
not worth you spending the effort coding something that will be ignored;
conversely, if a piece of info is so important that I end up hacking
procfs anyways, that says we have a hole in QMP. I'm okay waiting for now.
Assuming the list of to-do's for the next patch version remains minimal,
I'll go ahead and add support to return the access mode flags from
query-fdsets. Also, I'm going to remove in-use from the returned data,
because it is always going to be true.
