Some schmuck wants to get our stable-non-rebasing branch into upstreamable shape well before the next merge window. This series was issued a month ago! Sorry to crack the whip, but let's please all be aware or our upstreaming timing. > I will go through the series in depth, hopefully there will not be a need for > next version and in that case, please just resend the cover letter with the > information you provided below and don't worry about the length of the cover > letter. That's a plan. Happily, MGRLU changes are well-isolated so I was able to trivially move this series to the tail of mm-unstable. It isn't a problem at all for me to defer this until the next cycle - please let me know. I'd like to know this as early as possible so I can hide the series until after -rc1. We shouldn't have "not for next merge window" material in there possibly invalidating our ongoing testing.
