Subject: Re: [PATCH 000/141] Fix fall-through warnings for Clang

Well, I was curious about the former (obviously no tool will tell me
about the latter), so I asked git what patches had a fall-through
series named in a fixes tag and these three popped out:

9cf51446e686 bpf, powerpc: Fix misuse of fallthrough in bpf_jit_comp()
6a9dc5fd6170 lib: Revert use of fallthrough pseudo-keyword in lib/
91dbd73a1739 mips/oprofile: Fix fallthrough placement

I don't think any of these is fixing a significant problem, but they
did cause someone time and trouble to investigate.
