Yes, it may well do. The problem is the pool of XFS developers is *much smaller* than the graphics subsystem and so a "group maintainership" if kinda what we do already. I mean, I do have commit rights to the XFS trees kernel.org, even though I'm not a maintainer. I'm essentially the backup at this point - if someone needs to take time off, I'll take over. I think the biggest barrier to maintaining the XFS tree is the amount of integration testing that the maintainer does on the merged tree. That's non-trivial, especially with how long it takes to run fstests these days. If you're not set up to run QA 24x7 across a bunch of different configs, then you need to get that into place before being able to do the job of maintaining the XFS kernel tree... If everyone had that capability and resources at their disposal, then rotating the tree maintenance responsibilities would be much easier... Cheers, Dave. -- Dave Chinner david@fromorbit.com
