函数名称：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
函数原型：static void add_vma_to_mm(struct mm_struct *mm, struct vm_area_struct *vma)
返回类型：void
参数：
| 类型 | 参数 | 名称 |
|---|---|---|
| struct mm_struct * | mm | |
| struct vm_area_struct * | vma |
| 601 | number of VMAs 自加 |
| 605 | 如果File we map to (can be NULL). 则 |
| 608 | i_mmap_lock_write(mapping) |
| 610 | vma_interval_tree_insert(vma, & i_mmap) |
| 620 | pvma等于rb_entry(parent, structvm_area_struct, vm_rb) |
| 629 | 否则如果The first byte after our end addresswithin vm_mm. 小于The first byte after our end addresswithin vm_mm. 则p等于rb_left |
| 639 | 否则BUG() |
| 643 | rb_link_node( & vm_rb, parent, p) |
| 644 | rb_insert_color( & vm_rb, & mm_rb) |
| 647 | prev = NULL |
| 651 | __vma_link_list(mm, vma, prev) |
| 名称 | 描述 |
|---|---|
| do_mmap | handle mapping creation for uClinux |
| split_vma | split a vma into two pieces at address 'addr', a new vma is allocated either* for the first part or the tail. |
