    mm/page_owner: introduce split_page_owner and replace manual handling · a9627bc5
    Joonsoo Kim authored Jul 26, 2016
    split_page() calls set_page_owner() to set up page_owner to each pages.
    But, it has a drawback that head page and the others have different
    stacktrace because callsite of set_page_owner() is slightly differnt.
    To avoid this problem, this patch copies head page's page_owner to the
    others.  It needs to introduce new function, split_page_owner() but it
    also remove the other function, get_page_owner_gfp() so looks good to
    do.
