Type:unsigned long
Parameter:
| Type | Parameter | Name |
|---|---|---|
| pte_t | pte |
| 215 | Return (pfn & Extracts the PFN from a (pte|pmd|pud|pgd)val_t of a 4KB page ) >> PAGE_SHIFT determines the page size |
| Name | Describe |
|---|---|
| is_crashed_pfn_valid | |
| __replace_page | __replace_page - replace page in vma by new page |
| follow_page_pte | |
| get_gate_page | |
| vm_normal_page | vm_normal_page -- This function gets the "struct page" associated with a pte.* "Special" mappings do not wish to be associated with a "struct page" (either* it doesn't exist, or it exists but they don't want to touch it). In this |
| insert_pfn | |
| wp_page_reuse | Handle write page faults for pages that can be reused in the current vma* This can happen either due to the mapping being with the VM_SHARED flag,* or due to us being the last reference standing to the 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. |
| follow_pfn | llow_pfn - look up PFN at a user virtual address*@vma: memory mapping*@address: user virtual address*@pfn: location to store found PFN* Only IO mappings and raw PFN mappings are allowed.* Return: zero and the pfn at @pfn on success, -ve otherwise. |
| prot_none_pte_entry | |
| prot_none_hugetlb_entry | |
| check_pte | heck_pte - check if @pvmw->page is mapped at the @pvmw->pte* page_vma_mapped_walk() found a place where @pvmw->page is *potentially** mapped |
| page_mkclean_one | |
| try_to_unmap_one | @arg: enum ttu_flags will be passed to this argument |
| vmemmap_verify | |
| 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 |
