    [PATCH] page migration reorg · b20a3503
    Christoph Lameter 提交于
    Centralize the page migration functions in anticipation of additional
    tinkering.  Creates a new file mm/migrate.c
    
    1. Extract buffer_migrate_page() from fs/buffer.c
    
    2. Extract central migration code from vmscan.c
    
    3. Extract some components from mempolicy.c
    
    4. Export pageout() and remove_from_swap() from vmscan.c
    
    5. Make it possible to configure NUMA systems without page migration
       and non-NUMA systems with page migration.
    
    I had to so some #ifdeffing in mempolicy.c that may need a cleanup.
