What about this one: redefine it to (*ioctl)( ...., unsigned *long*, unsinged long). That means we can add #define IOCTL_COMPAT 0x1 0000 0000
Bzzt! Doesn't work on 32-bit. COMPAT does not mean 64-bit-->32-bit translations, stop thinking about the compat layer in this way.
It is a generic environment translation system.
Eventually we can use it for things like IBCS2 and stuff like that.
Suggest something sane like defining a macro such as "compat_task(tsk)" that can be tested by various bits of code. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
