Quoting <asm/ioctls.h>:

> #if defined(__USE_MISC) || defined (__KERNEL__)
> #define tIOC            ('t' << 8)
> #endif

Could somebody try to explain this to me?  I'm especially interested
in the #if part.  Why isn't tIOC defined normally?  It is used later.
in the file - and it is used externally by rp-pppoe for example.

Regards,

	Joey

Overly paranoid attempt at keeping the namespace cleaner than Mr Proper
himself.

I immediately commited it for both 2.2 and 2.4, mips and mips64.  You can
follow the commits on the linux-cvs@oss.sgi.com mailing lists.  Just
subscribe via Majordomo.
