Type:void
Parameter:
Type | Parameter | Name |

struct address_space * | mapping |
526 | lock for writing |
Name | Describe |
---|---|
dup_mmap | |
add_vma_to_mm | add a VMA into a process's mm_struct in the appropriate place in the list* and tree and add to the address space's page tree also if not an anonymous* page* - should be called with mm->mmap_sem held writelocked |
delete_vma_from_mm | delete a VMA from its owning mm_struct and address space |
unmap_single_vma | |
unmap_mapping_pages | map_mapping_pages() - Unmap pages from processes.*@mapping: The address space containing pages to be unmapped.*@start: Index of first page to be unmapped.*@nr: Number of pages to be unmapped. 0 to unmap to end of file. |
unlink_file_vma | Unlink a file-based vm structure from its interval tree, to hide* vma from rmap and vmtruncate before freeing its page tables. |
vma_link | |
__vma_adjust | We cannot adjust vm_start, vm_end, vm_pgoff fields of a vma that* is already present in an i_mmap tree without adjusting the tree.* The following helper function should be used when such adjustments* are necessary |
take_rmap_locks | |
unmap_ref_private | This is called when the original mapper is failing to COW a MAP_PRIVATE* mappping it owns the reserve page for. The intention is to unmap the page* from other VMAs and let the children be SIGKILLed if they are faulting the* same region. |
