函数名称：Test that we can read a two digit number in a sufficiently size buffer.* Nothing fancy.

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

返回类型：void

参数：

类型参数名称
struct kunit *test
186  data等于0
188  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, }
197  len等于4
198  pos等于0
199  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.
200  __user乘user_buffer等于buffer
202  *data等于13
204  KUNIT_EXPECT_EQ() - Sets an expectation that @left and @right are equal(test, 0, 读sysctl整数向量)
206  KUNIT_ASSERT_EQ() - Sets an assertion that @left and @right are equal(test, (size_t)3, len)
207  buffer[len]等于'\0'
209  KUNIT_EXPECT_STREQ() - Expects that strings @left and @right are equal(test, "13\n", buffer)
