兄弟，rbtree.c中exit函数，释放的有点。。尴尬。。

static void __exit my_exit(void) { struct mytype *data; struct rb_node *node; printk("The rbtree kernel is exiting!\n"); for (node = rb_first(&mytree); node; ) { data = rb_entry(node, struct mytype, node); if (data) { rb_erase(&data->node, &mytree); node = rb_next(node); kfree(data); } } }
