It looks like a fix for: Fixes: 0eb8a1c4c786 ("vfio: add request notifier interrupt") This fix probably qualifies for backport, but this code has been like this for a long time, with no report of a bug. Should we backport it? If there was no question on backporting it, I would apply it right away, since I saw no comment from maintainers for such a long time. I'll wait a bit more hoping to get a reply on my question on backporting. -- David Marchand
