函数名称：Test that proc_dointvec will not try to use a NULL .data field even when the* length is non-zero.

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

返回类型：void

参数：

类型参数名称
struct kunit *test
21  struct ctl_table null_data_table = { Text ID for /proc/sys, or zero = "foo", data = NULL, maxlen = sizeof(int), mode = 0644, Callback for text formatting = 读sysctl整数向量, extra1 = & i_zero, extra2 = & i_one_hundred, }
39  __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.
48  len等于1234
49  KUNIT_EXPECT_EQ() - Sets an expectation that @left and @right are equal(test, 0, 读sysctl整数向量)
52  KUNIT_EXPECT_EQ() - Sets an expectation that @left and @right are equal(test, (size_t)0, len)
57  len等于1234
58  KUNIT_EXPECT_EQ() - Sets an expectation that @left and @right are equal(test, 0, 读sysctl整数向量)
61  KUNIT_EXPECT_EQ() - Sets an expectation that @left and @right are equal(test, (size_t)0, len)
