Hi,

I want to define custom return values for my ioctl calls in my Kernel module.  What is the recommended start value for user defined constants?  I notice asm/errno.h only goes up to 124 (in 2.4.12), so should I start at 125 or should I start at 200 to be safe?

I probably only need 30 or so different codes.

Thanks,
