Its filename is mm-compaction-embed-migration-mode-in-compact_control-fix-fix.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/mm-compaction-embed-migration-mode-in-compact_control-fix-fix.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/mm-compaction-embed-migration-mode-in-compact_control-fix-fix.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/SubmitChecklist when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Joonsoo Kim <iamjoonsoo.kim@xxxxxxx> Subject: CMA: use MIGRATE_SYNC in alloc_contig_range() Before commit 'mm, compaction: embed migration mode in compact_control' from David is merged, alloc_contig_range() used sync migration, instead of sync_light migration. This doesn't break anything currently because page isolation doesn't have any difference with sync and sync_light, but it could in the future, so change back as it was. And pass cc->mode to migrate_pages(), instead of passing MIGRATE_SYNC to migrate_pages().
