Patches and Packaging for Erlang Components

Hello! I was able to use the experimental osmo_dia2gsup converter to successfully enable circuit switched fallback in a test network, but have a couple fixes for it and osmo_ss7 needed to work with the latest 2G CN components. I would open a change request in gerrit, but I see that the rebar.conf of osmo_dia2gsup already depends on a WIP branch from osmo_ss7. How best should I provide patches for review? Is there ongoing work in http://git.osmocom.org/erlang/osmo_ss7/log/?h=laforge/wip that needs to be merged first, and is there a reason it has not been merged already? Otherwise should I open a change request towards the WIP branch? Also, do folks have any opinions on how best to package erlang components? I was going to generate a Debian package for a stand-alone erlang “release” of osmo_dia2gsup, and am happy to contribute the debian metadata and build files upstream, but I am not an erlang expert and want to make sure it’s structured in the correct way if there is a convention I should follow. packaged, so I don’t have a good example to go from. If there is no opinion I will make an attempt, but I wanted to ask first! Thanks for your help and patience! -Matt J.
