So I talked about this with Sumit privately but I think
it might make sense to have me step down as maintainer when
this goes out of staging. I mostly worked on Ion at my
previous position and anything I do now is mostly a side
project. I still want to see it succeed which is why I
took on the maintainer role but I don't want to become blocking
for people who have a stronger vision about where this needs
to go (see also, I'm not working with this on a daily basis).

If you just want someone to help review or take patches
to be pulled, I'm happy to do so but I'd hate to become
the bottleneck on getting things done for people who
are attempting to do real work.

I worry this will make everyone to touch the side of their nose and
yell "NOT IT!" :)

First of all, thank you so much for your efforts maintaining ION along
with your attempts to drag out requirements from interested parties
and the numerous attempts to get collaborative discussion going at
countless conferences! Your persistence and continual nudging in the
face of apathetic private users of the code probably cannot be
appreciated enough!

Your past practical experience with ION and active work with the
upstream community made you a stand out pick for this, but I
understand not wanting to be eternally stuck with a maintainership if
your not active in the area. I'm happy to volunteer as a neutral
party, but I worry my limited experience with some of the more
complicated usage would make my opinions less informed then they
probably need to be. Further, as a neutral party, Sumit would
probably be a better pick since he's already maintaining the dmabuf
core.


Honestly if you're doing the work to re-write everything, I
think you're more than qualified to be the maintainer. I
would also support Sumit as well.

So I'd nominate Andrew, Liam or Benjamin (or all three?) as they all
have more practical experience enabling past ION heaps on real devices
and have demonstrated active interest in working in the community.


I do think this would benefit both from multiple maintainers and
from maintainers who are actively using the framework. Like I
said, I can still be a maintainer but I think having some comaintainers
would be very helpful (and I'd support any of the names you've
suggested)

So, in other words... NOT IT! :)

I think you have to shout "Noes goes" first. :)
