Hello there,

I've tried 4.9 and 5.2 and don't see this warning.
As expected - I used a development version of gcc.
Latest released version is 6.2
Is this 6.x gcc?
7.0 would be more accurate.
I suspect it will have such warnings all over the kernel.
Indeed it has hundreds, but the subject under discussion is file
kernel/bpf/verifier.c.
I am still not sure if I have found a fallthrough bug or not.
You haven't, this is intended so is a useless warning. Thanks,
Josef
