However, my understanding of LSF/MM is that this is not a "stand up and give a status or implementation experience report" kind of event. It's more of a "I have this specific itch that I need to get some help with." None of the above proposal strikes me as very specific, and a CIFS-centric talk would likely be unappealing to even most of the attendees of the Filesystems track. Can the proposed topic be rephrased as a focused discussion of what work needs to be moved forward, what decisions need to be made, and so on? Otherwise, we should move this topic to a network filesystems BoF or to the corridor track, IMHO. -- Chuck Lever
