Strange. I always thought that static inline functions do not cause warnings when not used? Especially, since they are often in headers when things are turned off. Or is it because this is in a C file? Is this a new warning caused by a commit, or is it a new warning because the compiler now complains about it? -- Steve > > > vim +/ftrace_startup_enable +7157 kernel/trace/ftrace.c
