I actually prefer "goto-less alternative 2". It's more verbose, but more explicit. No magic, I know exactly what happen. If you suddenly have more functions, you should have an array of functions with a clean_up_level variable. Of course, you probably should not have a global state that some clean up function with a side effect deals with in the first place, but it's the c linux kernel so I assume there is something I don't know.
