Hi Sits, thanks for your bug report. I've contacted upstream to ask about a new release version. If there isn't one coming soon I'll add the relevant patches to the SRPM rather than base the package on git.
Apologies for the delay, things went a bit quiet upstream for a while. Things are picking up now, though: iowatcher has just been merged into blktrace upstream* and released in blktrace 1.1.0 so I intend to work with the blktrace package maintainer to retire the iowatcher package and generate the rpm from the blktrace package in Fedora in future. * Thread starting http://marc.info/?l=linux-btrace&m=141158777908658&w=2
