Hi, this is the splitted-off first part of my "make direct compaction more deterministic" series [1], rebased on mmotm-2016-07-13-16-09-18. For the whole series it's probably too late for 4.8 given some unresolved feedback, but I hope this part could go in as it was stable for quite some time. At the very least, the first patch really shouldn't wait any longer.
