名称	描述
dup_mmap
dma_common_mmap	Create userspace mapping for the DMA-coherent memory.
dma_direct_mmap
__dma_mmap_from_coherent
vma_last_pgoff
__vm_map_pages	__vm_map_pages - maps range of kernel pages into user vma@vma: user vma to map to@pages: pointer to array of source kernel pages@num: number of pages in page array@offset: user's requested vm_pgoff
unmap_mapping_range_tree
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
can_vma_merge_after	Return true if we can merge this (vm_flags,anon_vma,file,vm_pgoff)* beyond (at a higher virtual address and file offset than) the vma.* We cannot merge two vmas if they have differently assigned (non-NULL)
remove_vma_list	Ok - we have the memory areas we should free on the vma list,* so release them, and do the vma updates.* Called with the mm semaphore held.
__do_munmap	Munmap is split into 2 main parts -- this part which finds* what needs doing, and the areas themselves, which do the* work. This now handles partial unmappings.* Jeremy Fitzhardinge
exit_mmap	Release all mmaps.
insert_vm_struct	Insert vm structure into process list sorted by address* and into the inode's i_mmap tree. If vm_file is non-NULL* then i_mmap_rwsem is taken here.
walk_page_mapping	walk_page_mapping - walk all memory areas mapped into a struct address_space
mpol_set_shared_policy
get_arg_page
