This is one patch on top of the series "Follow-up on high-order PCP caching" that is already in mmotm. The series left prefetching in place but as the batch freeing of PCP pages now all happens under the zone lock, it's unlikely there is enough time for the prefetching to have a benefit so remove it. mm/page_alloc.c | 24 ------------------------ 1 file changed, 24 deletions(-) -- 2.26.2
