Subject[PATCH 6/9] mm/compaction: rename is_via_compact_memory to compaction_with_allocation_order
Date
We have order = -1 via proactive compaction, the is_via_compact_memory is
not proper name anymore.
As cc->order informs the compaction to satisfy a allocation with that
order, so rename it to compaction_with_allocation_order.
