Subject[PATCH v2 0/4] enhance compaction success rate
Date
This patchset aims at increase of compaction success rate. Changes are 
related to compaction finish condition and freepage isolation condition.

From these changes, I did stress highalloc test in mmtests with nonmovable
order 7 allocation configuration, and compaction success rate (%) are

Base Patch-1 Patch-2 Patch-3 Patch-4
18.47 27.13 31.82 -- 42.20

Note: Base version is tested in v1 and the others are tested freshly.
Test is perform based on next-20150103 and Vlastimil's stealing logic
patches due to current next's unstablility.
Patch-3 isn't tested since there is no functional change.

Joonsoo (3):
mm/compaction: stop the isolation when we isolate enough freepage
mm/page_alloc: separate steal decision from steal behaviour part
mm/compaction: enhance compaction finish condition

Joonsoo Kim (1):
mm/compaction: fix wrong order check in compact_finished()
