Nothing wrong, but currently they are shown in "natural" points, i.e. in those that the controller accounts them in. For RSS controller the natural point is "page", but auto-converting them from pages to bytes is wrong, as not all the controllers account in pages. I think that the better way is to show the value in the internal units and specify (somehow) what these units are. The userspace then can read them and convert accordingly. > Paul Thanks, Pavel - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
