Why do that ? What about static_calls ? There may be files without ftrace but with static calls. By the way, it would be nice if we could use it only on C files. I get the following errors for ASM files: arch/powerpc/kernel/entry_32.o: warning: objtool: .text+0x1b4: unannotated intra-function call > > Signed-off-by: Naveen N.
