AFAIK, only regressions and fixes to severe bugs (QEMU crashes, hangs, CVEs) go
to stable QEMU releases. It doesn't seem to be the case for any of the commits
listed above but I had only a quick look.

Hmm good question. I'm usually notified when Michael posts the patch round-up
and a 9p patch is already in the list, like for the present patch. Other than
that I watch qemu-stable from time to time or the planning pages in the wiki.
Michael, anything better to suggest to Christian ?
