1.挂载vmacache_find，这个函数在VMA缓存中查找。挂载find_vma，跟踪查找虚拟内存区域的操作。VMACache Hit有助于评估虚拟内存缓存的命中率；Duration是查找操作的持续时间，可以用来评估内存管理的效率；RB Subtree Last是红黑树中的最后节点值，它为0表示节点没有子树或子树为空。
2.挂载insert_vm_struct，这个函数插入虚拟内存结构体。Duration是插入操作的持续时间，用来评估内存管理系统在处理插入操作时的性能；List Time、 RB Time、Interval Tree Time 分别表示插入操作在链表、红黑树、基数树中所需时间。
