函数名称：__ksize -- Uninstrumented ksize

函数原型：size_t __ksize(const void *objp)

返回类型：size_t

参数：

类型参数名称
const void *objp
4270  BUG_ON(!objp)
4271  如果此条件成立可能性小(为编译器优化)(objp == ZERO_SIZE_PTR will be returned for zero sized kmalloc requests.* Dereferencing ZERO_SIZE_PTR will lead to a distinct access fault.* ZERO_SIZE_PTR can be passed to kfree though in the same way that NULL can.* Both make kfree a no-op.)则返回:0
4274  c等于virt_to_cache(objp)
4275  size等于如果c则The size of an object without metadata 否则0
4277  返回:size
