These are two patches are meant to go on top of the rest of the compiler attributes series on:
https://github.com/ojeda/linux/tree/compiler-attributes which will be sent to Greg for the next merge window. Please review them and let me know! (specially if someone is against __fallthrough for some reason :-). The first patch introduces the attribute and gives the rationale. The second patch is an example of usage.
