函数名称：Here we provide a valid struct ctl_table, but we try to read and write from* it using a buffer of zero length, so it should still fail in a similar way as* before.

函数原型：static void sysctl_test_api_dointvec_table_len_is_zero(struct kunit *test)

返回类型：void

参数：

类型参数名称
struct kunit *test
117  data等于0
119  struct ctl_table table = { Text ID for /proc/sys, or zero = "foo", data = & data, maxlen = sizeof(int), mode = 0644, Callback for text formatting = 读sysctl整数向量, extra1 = & i_zero, extra2 = & i_one_hundred, }
128  __user乘buffer等于kunit_kzalloc() - Just like kunit_kmalloc(), but zeroes the allocation.*@test: The test context object.*@size: The size in bytes of the desired memory.*@gfp: flags passed to underlying kmalloc().* See kzalloc() and kunit_kmalloc() for more information.
133  len等于0
136  KUNIT_EXPECT_EQ() - Sets an expectation that @left and @right are equal(test, 0, 读sysctl整数向量)
138  KUNIT_EXPECT_EQ() - Sets an expectation that @left and @right are equal(test, (size_t)0, len)
140  KUNIT_EXPECT_EQ() - Sets an expectation that @left and @right are equal(test, 0, 读sysctl整数向量)
142  KUNIT_EXPECT_EQ() - Sets an expectation that @left and @right are equal(test, (size_t)0, len)
