If you send me the same patch, I can do submit a request to the devel
package for openSUSE. I don't have commit access but I would be surprised
if the package maintainer didn't accept the request. Obviously, I'll
build+boot a kernel that includes the final version of this series in
case of any naming changes or other oddities.

Good thinking. I'll open a bug on github when I've tested your iotop
patch so that the bug report is more coherent.

Thanks for the quick response.
