Hi all,

	is there any reason why ioctls TIOCGRS485 and TIOCSRS485 are defined (with the same values) in both include/asm-generic/ioctls.h and arch/arm/include/asm/ioctls.h ?

The same happens also for avr32, powerpc and cris (which, however, defines a different value for TIOCSRS485).

Is it duplicated code ?

Or should these values stay in both asm/ioctls.h and asm-generic/ioctls.h ?

Many thanks,

	Claudio

Please wrap your message sensibly so I can see it while replying to you.

As an exercise to help you answer your own question, please research
how asm-generic/ioctls.h get included on an avr32, powerpc, cris or
ARM kernel build.
