I've uploaded two scripts here:
http://people.valinux.co.jp/~ryov/dm-ioband/scripts/xdd-count.sh
http://people.valinux.co.jp/~ryov/dm-ioband/scripts/xdd-size.sh
xdd-count.sh controls bandwidth based on the number of I/O requests,
and xdd-size.sh controls bandwidth based onthe number of I/O sectors.
Theses scritpts require xdd disk I/O testing tool which can be
downloaded from here:
http://www.ioperformance.com/products.htm
Please feel free to ask me questions if you have any questions.

Thanks, but your patch seems to cause a problem when ioband devices
which have the same name are created at the same time. I will fix the
issue in the next release.
Thanks,
Ryo Tsuruta
