返回类型：void

参数：

类型参数名称
struct kunit *test
347  data等于0
348  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, }
357  max_len等于32, len等于max_len
358  pos等于0
359  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.
360  __user乘user_buffer等于buffer
361  greater_than_max等于INT_MAX加1
363  KUNIT_ASSERT_GT() - An assertion that @left is greater than @right(test, greater_than_max, (unsignedlong)INT_MAX)
364  KUNIT_ASSERT_LT() - An assertion that @left is less than @right(test, (size_t)snprintf - Format a string and place it in a buffer*@buf: The buffer to place the result into*@size: The size of the buffer, including the trailing null space*@fmt: The format string to use*@, max_len)
367  KUNIT_EXPECT_EQ() - Sets an expectation that @left and @right are equal(test, - EINVAL, 读sysctl整数向量)
369  KUNIT_ASSERT_EQ() - Sets an assertion that @left and @right are equal(test, max_len, len)
370  KUNIT_EXPECT_EQ() - Sets an expectation that @left and @right are equal(test, 0, * ((int * )data))
