Name:Test that proc_dointvec refuses to read when the file position is non-zero.

Proto:static void sysctl_test_api_dointvec_table_read_but_position_set(struct kunit *test)

Type:void

Parameter:

TypeParameterName
struct kunit *test
151  data = 0
153  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, }
162  __user * 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.
168  len = 1234
173  pos = 1
175  KUNIT_EXPECT_EQ() - Sets an expectation that @left and @right are equal(test, 0, read a vector of integers)
177  KUNIT_EXPECT_EQ() - Sets an expectation that @left and @right are equal(test, (size_t)0, len)
