Chuyi Zhou 7efc3b7261 mm/compaction: fix set skip in fast_find_migrateblock ... When we successfully find a pageblock in fast_find_migrateblock(), the block will be set skip-flag through set_pageblock_skip(). However, when entering isolate_migratepages_block(), the whole pageblock will be skipped due to the branch 'if (!valid_page && IS_ALIGNED(low_pfn, pageblock_nr_pages))'. Eventually we will goto isolate_abort and isolate nothing. That makes fast_find_migrateblock useless. In this patch, when we find a suitable pageblock in fast_find_migrateblock, we do noting but let isolate_migratepages_block to set skip flag to the pageblock after scan it. Normally, we would isolate some pages from the fast-find block. I use mmtest/thpscale-madvhugepage test it. Here is the result: baseline patch Amean fault-both-1 1331.66 ( 0.00%) 1261.04 * 5.30%* Amean fault-both-3 1383.95 ( 0.00%) 1191.69 * 13.89%* Amean fault-both-5 1568.13 ( 0.00%) 1445.20 * 7.84%* Amean fault-both-7 1819.62 ( 0.00%) 1555.13 * 14.54%* Amean fault-both-12 1106.96 ( 0.00%) 1149.43 * -3.84%* Amean fault-both-18 2196.93 ( 0.00%) 1875.77 * 14.62%* Amean fault-both-24 2642.69 ( 0.00%) 2671.21 * -1.08%* Amean fault-both-30 2901.89 ( 0.00%) 2857.32 * 1.54%* Amean fault-both-32 3747.00 ( 0.00%) 3479.23 * 7.15%* Link: https://lkml.kernel.org/r/20220713062009.597255-1-zhouchuyi@bytedance.com Fixes: 70b44595ea ("mm, compaction: use free lists to quickly locate a migration source") Signed-off-by: zhouchuyi <zhouchuyi@bytedance.com> Cc: Mel Gorman <mgorman@techsingularity.net> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>		2022-10-12 15:56:45 -07:00
