Fine. A Fixes: for 3 & 4 would be good. Otherwise we're potentially asking for those to be backported further than 1 & 2, which seems wrong. Then again, by having different Fixes: in the various patches we're suggesting that people split the patch series apart as they slot things into the indicated places. In other words, it's not a patch series at all - it's a sprinkle of independent fixes. Are we OK thinking of it in that fashion?
