It will be old, unneeded cruft. Don't accumulate cruft. If we possibly can remove the old stuff, we should. It's what we do. Maybe in five years we'll find we can't remove them. We'll see. At least we tried. Hopefully by then none of these interfaces will be in use anyway. -- 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/
