Subject[PATCH 0/8] compaction-related cleanups v5
Date
Changes since v4:
- Patch 4 - skip initial compaction when allowed to ignore watermarks (DavidR)
- Rebased to mmotm-2016-07-18-16-40-20
- Acks by Mel Gorman, Michal Hocko, David Rientjes - Thanks!

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.
