They usually use the standard major/minor/ makedev macros, so you only get back what the platform supports. Splitting dev_t in major/minor numbers can be lots of fun... bye, Roman - 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/
