Subject: [RFC 0/4] try to reduce fragmenting fallbacks

Hi Johannes,

here's something quick to try or ponder about. However, untested since it's too
late here. Based on mmotm-2016-09-27-16-08 plus this fix [1]

[1] http://lkml.kernel.org/r/<cadadd38-6456-f58e-504f-cc18ddc47b3f@...e.cz>

Vlastimil Babka (4):
  mm, compaction: change migrate_async_suitable() to
    suitable_migration_source()
  mm, compaction: add migratetype to compact_control
  mm, compaction: restrict async compaction to matching migratetype
  mm, page_alloc: disallow migratetype fallback in fastpath

 include/linux/mmzone.h |  5 +++++
 mm/compaction.c        | 41 +++++++++++++++++++++++++----------------
 mm/internal.h          |  2 ++
 mm/page_alloc.c        | 34 +++++++++++++++++++++++-----------
