#     kprobe/ftrace: fix build error due to bad function definition
#     
#     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.
