mm, compaction: terminate async compaction when rescheduling
commit aeef4b83806f49a0c454b7d4578671b71045bee2 upstream.
Async compaction terminates prematurely when need_resched(), see
compact_checklock_irqsave(). This can never trigger, however, if the
cond_resched() in isolate_migratepages_range() always takes care of the
scheduling.
If the cond_resched() actually triggers, then terminate this pageblock
scan for async compaction as well.
