| 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. |
| do_cow_fault | |
| unuse_pte | No need to decide whether this PTE shares the swap entry with others,* just let do_wp_page work it out if a write is requested later - to* force COW, vm_page_prot omits write permission from any private vma. |
