Re: [PATCH] arch: powerpc: kernel: signal_32.c: Remove unused function

Hi

Ok, sorry :-(

But I really do not. I've hacked together a script that will scan all
the code for the function, and test builds with some different config
options turned on.


Kind regards

Remove the function sys_debug_setcontext() that is not used anywhere.

This was partially found by using a static code analysis program called cppcheck.

Please don't blindly trust code analysis tools.
The function you're removing *is* in use.

  LD      init/built-in.o
arch/powerpc/kernel/built-in.o: In function `sys_call_table':
(.rodata+0x744): undefined reference to `sys_debug_setcontext'
