# Commit 1a7d0890dd4a ("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. # # Fixes: 1a7d0890dd4a kprobe/ftrace: bail out if ftrace was killed # Cc: Stephen Brennan <stephen.s.brennan@oracle.com> # Cc: Masami Hiramatsu (Google) <mhiramat@kernel.org> #
