* doc: mm: migration doesn't use FOLL_SPLIT anymoreYang Shi2019-04-191-7/+1Star
| | | | | | | | | | | | | | | | When demonstrating FOLL_SPLIT in transhuge document, migration is used as an example. But, since commit 94723aafb9e7 ("mm: unclutter THP migration"), the way of THP migration is totally changed. FOLL_SPLIT is not used by migration anymore due to the change. Remove the obsolete example to avoid confusion. Cc: Michal Hocko <mhocko@suse.com> Cc: Kirill A.
