Kernel prepatch 4.8-rc7

The 4.8-rc7 kernel prepatch is out."Normally rc7 is the last in the series before the final release, butby now I'm pretty sure that this is going to be one of those releases thatcome with an rc8. Things did't calm down as much as I would have liked,there are still a few discussions going on, and it's just unlikely that Iwill feel like it's all good and ready for a final 4.8 next Sunday."
