Re: [PATCH] mm,page_alloc: PF_WQ_WORKER threads must sleep at should_reclaim_retry().

[Michal Hocko]

This change has been posted several times with some concerns about the
changelog. Originally I thought it is more of a "nice to have" thing
rather than a bug fix, later Tetsuo has taken over it but the changelog
was not really comprehensible so I reworded it. Let's see if this is
better.
