commit 4b377b4868 upstream.
Commit 1a7d0890dd ("kprobe/ftrace: bail out if ftrace was killed")
introduced a bad K&R function definition, which we haven't accepted in a
long long time.
Gcc seems to let it slide, but clang notices with the appropriate error:
kernel/kprobes.c:1140:24: error: a function declaration without a prototype is deprecated in all >
1140 | void kprobe_ftrace_kill()
| ^
| void
but this commit was apparently never in linux-next before it was sent
upstream, so it didn't get the appropriate build test coverage.
