Okay, so I look into updating the package. Can take a while, I hope to come to it next week. I will then close this bug via changelog entry. Prior to having it uploaded I would like to have the patch compiled and tested. Nobuhiro can you do it on SuperH? If need be, I can update the debian git repo for fio first. Hopefully next week.
