The loop should be waiting for the _other_ processes (doing direct reclaims) to proceed. When there are _lots of_ ongoing page allocations/reclaims, it makes sense to wait for them to calm down a bit?
I have noticed that if I run other process, it helps the loop to exit. So is this (ie hanging until other process helps) intended behaviour? Also, the other process does help the loop to exit, but again it enters the loop and the compaction is never finished. That is, the process looks like hanging. Is this intended behaviour? What will improve this situation?
