Name | Describe |

follow_pfn_pte | |
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. |
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_anonymous_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 mmap_sem still held, but pte unmapped and unlocked. |
alloc_set_pte | alloc_set_pte - setup new PTE entry for given page and add reverse page* mapping |
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) |
