From 4b377b4868ef17b040065bd468668c707d2477a5 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Fri, 17 May 2024 19:17:55 -0700 Subject: [PATCH] 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.
