sysctl_test_api_dointvec_null_tbl_data	Test that proc_dointvec will not try to use a NULL .data field even when the* length is non-zero.
sysctl_test_api_dointvec_table_maxlen_unset	Similar to the previous test, we create a struct ctrl_table that has a .data* field that proc_dointvec cannot do anything with; however, this time it is* because we tell proc_dointvec that the size is 0.
sysctl_test_api_dointvec_table_len_is_zero	Here we provide a valid struct ctl_table, but we try to read and write from* it using a buffer of zero length, so it should still fail in a similar way as* before.
sysctl_test_api_dointvec_table_read_but_position_set	Test that proc_dointvec refuses to read when the file position is non-zero.
sysctl_test_dointvec_read_happy_single_positive	Test that we can read a two digit number in a sufficiently size buffer.* Nothing fancy.
sysctl_test_dointvec_read_happy_single_negative	Same as previous test, just now with negative numbers.
sysctl_test_dointvec_write_happy_single_positive	Test that a simple positive write works.
sysctl_test_dointvec_write_happy_single_negative	Same as previous test, but now with negative numbers.
sysctl_test_api_dointvec_write_single_less_int_min	Test that writing a value smaller than the minimum possible value is not* allowed.
sysctl_test_api_dointvec_write_single_greater_int_max	Test that writing the maximum possible value works.
