Contrary to popular reputation, there are a handful of use cases where "goto" makes the code simpler, cleaner, more readable, and (in rarer cases) faster. In these cases, you should use goto statements. A good programmer can recognize these cases and use goto appropriately. Goto is never necessary in a strict sense but occasionally it can eliminate some pretty ugly spaghetti code.
The use cases for goto I see are primarily complex/thorough error handling (e.g. unwinding some concurrency control mechanisms) and certain low-level state machine patterns. I would expect to see these kinds of use cases in the Linux kernel.
