Hi!
So as far as I can tell we depend here on a fact that upper part of $rdx is zeroed. Not sure if that is guaranteed or not.
Which seems to be the case for x86_64 processors, so passing int value to ioctl() will work fine there. Not sure about the rest of 64bit archs. -- Cyril Hrubis chrubis-AlSwsSmVLrQ@public.gmane.org -- To unsubscribe from this list: send the line "unsubscribe linux-man" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
