I am able to commit to the iotop repository but I don't have permission
from the author to make releases nor do I have access to the website.

I am happy to apply any patches anyone has for iotop and upload the
result to Debian, or I'll be willing to write patches to cope with
changes in Linux behaviour, if given a succinct explanation of what
changes are needed in iotop, once the Linux changes are fully merged.

As well as the Python iotop implementation, there is one written in C 
with more features, so please also file an issue or pull request there.
Please note that I don't have commit access to that repository though.
