Subject: [PATCH] Hugetlb: Rename find_lock_page to find_or_alloc_huge_page
X-Git-Tag: v2.6.16-rc1~936^2~275

[PATCH] Hugetlb: Rename find_lock_page to find_or_alloc_huge_page

find_lock_huge_page() isn't a great name, since it does extra things not
analagous to find_lock_page().  Rename it find_or_alloc_huge_page() which is
closer to the mark.
