Add the following 2 scenarios to the allocinfo ioctl kselftest: 1. Validate size based filtering 2. Validate lineno based filtering The first test uses "do_init_module" as the candidate function for the test. This is because the associated site will only allocate memory when a kernel module is loaded. The return value of get_content_id() changes every time modules are loaded or unloaded. Hence, as long as get_content_id() values at the start and the end of the test are the same, the memory allocated by the do_init_module call site should also remain the same. Consequently, the test can assume consistency between the value returned by the ioctl and the procfs resulting in less flakiness.
