In the past year we had some friction with regards to the policies and the procedures around picking patches for stable tree, and I feel it would be very useful to establish better flow with the folks who might be attending LSF/MM. I feel that fs/ and mm/ are in very different places with regards to which patches go in -stable, what tests are expected, and the timeline of patches from the point they are proposed on a mailing list to the point they are released in a stable tree. Therefore, I'd like to propose two different sessions on this (one for fs/ and one for mm/), as a common session might be less conductive to agreeing on a path forward as the starting point for both subsystems are somewhat different. We can go through the existing processes, automation, and testing mechanisms we employ when building stable trees, and see how we can improve these to address the concerns of fs/ and mm/ folks. -- Thanks, Sasha
