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

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.
