seq-files just use printk() for text output. Not well-suited to binary output. Similarly, sysfs is desirable in some circumstances, but not for blocks of binary data. ioctls or netlink or debugfs or relay output (see how blktrace uses relay output) are your choices (I may have missed some. :) ioctls can be OK for some purposes. If you want to avoid them, try debugfs or relay. (I haven't looked at debugfs very much; it may be more text-oriented also...) --- ~Randy - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
