	Chris suggested providing more granularity for distributions (instead of "RHEL 6.X", do "RHEL 6.1", 6.2, 6.3, etc.). Might be nice to know, but would make a very crowded set of radio boxes. Peter will consider it, but can stick to current question style if it would make the survey too cluttered.

	James asked if LU-1812 (Fedora 18 support) could still land after the "feature freeze" date. Peter said that LU-1812 is considered a "minor enhancement", and since it is well on its way to completion and has little to no impact on the rest of the code, it is not constrained by the "feature freeze" date.

	Andreas asked about the two competing FC18/SP2 patche series. James reported that they are working together and have consolidated most of their work. Some patches for ldiskfs not yet merged, but in the works.		Andreas asked about the two competing FC18/SP2 patche series.

	James asked about patchless server for 2.4. We are close to patchless, but it looks like 2.4 will not quite eliminate the patches. Therefore the FC18/SP2 patches should be included.

	Andreas mentioned that Xyratex submitted mdraid patches to add to the kernel patch series. Those have a good chance to land for 2.4. When we go patchless, they'll need to move somewhere else. Would be nice if Xyratex can get those patches landed upstream.		Andreas mentioned that Xyratex submitted mdraid patches to add to the kernel patch series. Those have a good chance to land for 2.4.
