函数名称:look up the first VMA exactly that exactly matches addr* - should be called with mm->mmap_sem at least held readlocked
函数原型:static struct vm_area_struct *find_vma_exact(struct mm_struct *mm, unsigned long addr, unsigned long len)
返回类型:struct vm_area_struct
参数:
类型 | 参数 | 名称 |
---|---|---|
struct mm_struct * | mm | |
unsigned long | addr | |
unsigned long | len |
761 | vma等于vmacache_find_exact(mm, addr, end) |
768 | 如果Our start address within vm_mm. 小于addr则继续下一循环 |
770 | 如果Our start address within vm_mm. 大于addr则返回:NULL |
773 | vmacache_update(addr, vma) |
774 | 返回:vma |
778 | 返回:NULL |
