regzbot will notice when the patch hit's Linux next, where many changes
land and hang around for a few days before they hit mainline. Watching
all the different development trees would be possible and would catch
this patch earlier, but I'm not sure that's worth the work. Maybe
regzbot will do that one day, but there are more important missing
features on my todo list for now.
