cow_user_page
wp_page_copy	Handle the case of a page which we actually need to copy to a new page.* Called with mmap_sem locked and the old page referenced, but* without the ptl held.* High level logic flow:* - Allocate a page, copy the content of the old page to the new one.
finish_mkwrite_fault	sh_mkwrite_fault - finish page fault for a shared mapping, making PTE* writeable once the page is prepared@vmf: structure describing the fault This function handles all that is needed to finish a write page fault in a
do_wp_page	This routine handles present pages, when users try to write* to a shared page. It is done by copying the page to a new address* and decrementing the shared-page counter for the old page.* Note that this routine assumes that the protection checks have been
do_swap_page	We enter with non-exclusive mmap_sem (to exclude vma changes,* but allow concurrent faults), and pte mapped but not yet locked.* We return with pte unmapped and unlocked.* We return with the mmap_sem locked or unlocked in the same cases
do_numa_page
handle_pte_fault	These routines also need to handle stuff like marking pages dirty* and/or accessed for architectures that don't do it in hardware (most* RISC architectures)
pte_same_as_swp
hugetlb_cow	Hugetlb_cow() should be called with page lock of the original hugepage held.* Called with hugetlb_instantiation_mutex held and pte_page locked so we* cannot race with other handlers or page migration.
hugetlb_fault
replace_page	place_page - replace page in vma by new ksm page@vma: vma that holds the pte pointing to page@page: the page we are replacing by kpage@kpage: the ksm page we replace page by@orig_pte: the original value of the pte
