Cover letter [PATCH 0/9] mark expected switch fall-throughs
In preparation to enabling -Wimplicit-fallthrough, this patchset aims to mark switch cases where we are expecting to fall through.
In Kees Cook words:
"This is an unfortunate omission in the C language, and thankfully both gcc and clang have stepped up to solve this the same way static analyzers have solved it. It does both document the intention for humans and provide a way for analyzers to report issues.
Having the compiler help us not make mistakes is quite handy."
In some cases there were "else FALL THROUGH" or "then fallthrough..." comments already in place. So I replaced them with proper "fall through" comments, which is what GCC is expecting to find.
Thanks!
