函数名称:Same as mmu_notifier_register but here the caller must hold the mmap_sem in* write mode. A NULL mn signals the notifier is being registered for itree* mode.
函数原型:int __mmu_notifier_register(struct mmu_notifier *mn, struct mm_struct *mm)
返回类型:int
参数:
类型 | 参数 | 名称 |
---|---|---|
struct mmu_notifier * | mn | |
struct mm_struct * | mm |
569 | struct mmu_notifier_mm * mmu_notifier_mm = NULL |
572 | lockdep_assert_held_write( & mmap_sem) |
582 | 如果非mmu_notifier_mm则 |
588 | mmu_notifier_mm等于分配内存并置零 |
590 | 如果非mmu_notifier_mm则返回:负ENOMEM |
595 | invalidate_seq等于2 |
596 | itree = |
597 | init_waitqueue_head( & wq) |
598 | INIT_HLIST_HEAD( & deferred_list) |
602 | 如果此条件成立可能性小(为编译器优化)(ret)则转到:out_clean |
623 | 如果mn则 |
632 | 否则has_itree = true |
637 | 返回:0 |
639 | out_clean : |
640 | 释放内存 |
641 | 返回:ret |
