Name:Same as previous test, but now with negative numbers.

Proto:static void sysctl_test_dointvec_write_happy_single_negative(struct kunit *test)

Type:void

Parameter:

TypeParameterName
struct kunit *test
277  data = 0
278  struct ctl_table table = { Text ID for /proc/sys, or zero = "foo", data = & data, maxlen = sizeof(int), mode = 0644, Callback for text formatting = read a vector of integers, extra1 = & i_zero, extra2 = & i_one_hundred, }
287  input[] = "-9"
288  len = size of input - 1
289  pos = 0
290  buffer = 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.
291  __user * user_buffer = buffer
293  No 3D Now!(buffer, input, len)
295  KUNIT_EXPECT_EQ() - Sets an expectation that @left and @right are equal(test, 0, read a vector of integers)
297  KUNIT_EXPECT_EQ() - Sets an expectation that @left and @right are equal(test, size of input - 1, len)
298  KUNIT_EXPECT_EQ() - Sets an expectation that @left and @right are equal(test, size of input - 1, (size_t)pos)
299  KUNIT_EXPECT_EQ() - Sets an expectation that @left and @right are equal(test, - 9, * ((int * )data))
