    [PATCH] hugetlb: demand fault handler · 4c887265
    Adam Litke 提交于
    Below is a patch to implement demand faulting for huge pages.  The main
    motivation for changing from prefaulting to demand faulting is so that huge
    page memory areas can be allocated according to NUMA policy.
    
    Thanks to consolidated hugetlb code, switching the behavior requires changing
    only one fault handler.  The bulk of the patch just moves the logic from
    hugelb_prefault() to hugetlb_pte_fault() and find_get_huge_page().
