[PATCH 0/4] followups to reintroduce compaction feedback for OOM decisions

[Vlastimil Babka <vbabka@suse.cz>]

Reviews of series "reintroduce compaction feedback for OOM decisions" [1]
resulted in some followup patches and Michal suggested posting them in a new
threads, so here it goes.

Patch 1 is meant to be squashed into the following patch in mmotm:
mm-compaction-more-reliably-increase-direct-compaction-priority.patch

Patch 2 is a cleanup for consistency. Patches 3 and 4 deal with the last
(hopefully) remaining heuristic in the reclaim/compaction-vs-OOM scenario,
which is the fragmentation index.

Vlastimil Babka (4):
  mm, compaction: more reliably increase direct compaction priority-fix
  mm, page_alloc: pull no_progress_loops update to
    should_reclaim_retry()
  mm, compaction: ignore fragindex from compaction_zonelist_suitable()
  mm, compaction: restrict fragindex to costly orders
