函数名称：Test that a simple positive write works.

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

返回类型：void

参数：

类型参数名称
struct kunit *test
246  data等于0
248  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, }
257  input[]等于"9"
258  len等于input的长度减1
259  pos等于0
260  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.
261  __user乘user_buffer等于buffer
263  内存复制(buffer, input, len)
265  KUNIT_EXPECT_EQ() - Sets an expectation that @left and @right are equal(test, 0, 读sysctl整数向量)
267  KUNIT_EXPECT_EQ() - Sets an expectation that @left and @right are equal(test, input的长度 - 1, len)
268  KUNIT_EXPECT_EQ() - Sets an expectation that @left and @right are equal(test, input的长度 - 1, (size_t)pos)
269  KUNIT_EXPECT_EQ() - Sets an expectation that @left and @right are equal(test, 9, * ((int * )data))
