follow_page_pte | |
get_gate_page | |
copy_pte_range | |
zap_pte_range | |
insert_page | This is the old fallback for page remapping.* For historical reasons, it only allows reserved pages. Only* old drivers should use this, and they needed to mark their* pages reserved for the old functions anyway. |
insert_pfn | |
remap_pte_range | maps a range of physical memory into the requested pages. the old* mappings are removed. any references to nonexistent pages results* in null mappings (currently treated as "copy-on-access") |
apply_to_pte_range | |
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 |
do_fault_around | do_fault_around() tries to map few pages around the fault address. The hope* is that the pages will be needed soon and this will lower the number of* faults to handle.* It uses vm_ops->map_pages() to map the pages, which skips the page if it's |
do_fault | We enter with non-exclusive mmap_sem (to exclude vma changes,* but allow concurrent faults) |
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) |
mincore_pte_range | |
move_ptes | |
page_vma_mapped_walk | page_vma_mapped_walk - check if @pvmw->page is mapped in @pvmw->vma at*@pvmw->address*@pvmw: pointer to struct page_vma_mapped_walk. page, vma, address and flags* must be set. pmd, pte and ptl must be NULL.* Returns true if the page is mapped in the vma |

madvise_cold_or_pageout_pte_range | |

swap_vma_readahead | swap_vma_readahead - swap in pages in hope we need them soon*@entry: swap entry of this memory*@gfp_mask: memory allocation flags*@vmf: fault information* Returns the struct page for entry and addr, after queueing swapin.* Primitive swap readahead code |
