Yeah, hotfixes come first and separately please. A hotfix will hit mainline in a week or so. Whether or not they are cc:stable. The not-hotfix material won't hit mainline for as long as two months! So mixing hotfixes with next-merge-window patches is to be avoided. Note that a "hotfix" may or may not be cc:stable - it depends on whether the Fixes: commit was present in earlier kernel releases. Actually, if a developer has a hotfix as well as a bunch of next-merge-window material then it's really best to send the hotfix only. Hold off on the next-merge-window material so the hotfix gets standalone testing. Because it's possible that the next-merge-window material accidentally fixes an issue in the hotfix. (otoh the hotfixes *will* get that standalone testing from people who test Linus-latest, but it's bad of us to depend on that!) I regularly get patchsets which mix hotfixes (sometimes cc:stable) with next-merge-window material. Pretty often the hotfix isn't very urgent so I'll say screwit and merge it all as-is, after adding a cc:stable. The hotfix will get merged and backported eventually. I hope that nobody really needs to worry much about all this stuff. Juggling patch priority and timing is what akpms are for.
