函数名称：do_kmem_cache_size_bulk

函数原型：static int __init do_kmem_cache_size_bulk(int size, int *total_failures)

返回类型：int

参数：

类型参数名称
intsize
int *total_failures
321  maxiter等于1024
323  bool fail = false
326  c等于创建高速缓存区
327  以iter小于maxiter且非fail循环
328  num等于kmem_cache_alloc_bulk(c, GFP_KERNEL, ARRAY_SIZE - get the number of elements in array @arr*@arr: array to be sized(objects), objects)
330  以i小于num循环
331  bytes等于Calculate the number of uninitialized bytes in the buffer.
332  如果bytes则fail = true
334  fill_with_garbage(objects[i], size)
337  如果num则kmem_cache_free_bulk(c, num, objects)
340  total_failures加等于fail
341  返回:1
