[PATCH 0/9] Fixes and cleanups to compaction

[Kemeng Shi]

Hi all, this is another series to do fix and clean up to compaction.
Patch 1-2 fix and clean up freepage list operation.
Patch 3-4 fix and clean up isolation of freepages
Patch 7-9 factor code to check if compaction is needed for allocation
order.
More details can be found in respective patches. Thanks!

Kemeng Shi (9):
  mm/compaction: use correct list in move_freelist_{head}/{tail}
  mm/compaction: call list_is_{first}/{last} more intuitively in
    move_freelist_{head}/{tail}
  mm/compaction: correctly return failure with bogus compound_order in
    strict mode
  mm/compaction: simplify pfn iteration in isolate_freepages_range
  mm/compaction: remove repeat compact_blockskip_flush check in
    reset_isolation_suitable
  mm/compaction: rename is_via_compact_memory to
    compaction_with_allocation_order
  mm/compaction: factor out code to test if we should run compaction for
    target order
  mm/compaction: call compaction_suit_allocation_order in
    kcompactd_node_suitable
  mm/compaction: call compaction_suit_allocation_order in
    kcompactd_do_work
