返回类型:unsigned long
参数:
类型 | 参数 | 名称 |

struct vm_area_struct * | vma |
2482 | 返回:The first byte after our end addresswithin vm_mm. 减Our start address within vm_mm. 右移PAGE_SHIFT determines the page size 位 |

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 |
