Type:void
Parameter:
Type | Parameter | Name |
---|---|---|
struct vm_area_struct * | vma |
662 | curr = current process |
664 | number of VMAs -- |
665 | When i < VMACACHE_SIZE cycle |
668 | vmacache_invalidate(mm) |
669 | Break |
674 | If File we map to (can be NULL). Then |
677 | i_mmap_lock_write(mapping) |
679 | vma_interval_tree_remove(vma, & i_mmap) |
687 | __vma_unlink_list(mm, vma) |
Name | Describe |
---|---|
split_vma | split a vma into two pieces at address 'addr', a new vma is allocated either* for the first part or the tail. |
shrink_vma | shrink a VMA by removing the specified chunk from either the beginning or* the end |
do_munmap | lease a mapping* - under NOMMU conditions the chunk to be unmapped must be backed by a single* VMA, though it need not cover the whole VMA |
exit_mmap | lease all the mappings made in a process's VM space |
