lol

Actually I think it was a lot of effort from many people to monitor
and stay on top of conflicts, and there was certainly a deliberate
effort to bring many people together.

About the only thing I could concretely suggest for working with -mm
is if there was some way the -mm quilt patches could participate in
'git merge' resolution at your level.

I only say this because the lowest point was when merging CH's series
to hmm.git caused Andrew to have to do a lot of work rebasing DanW's
series during rc7. Arguably that should have been my work preparing a
conflict resolution instruction, not his doing rebases.

.. and if we needed to revise hmm.git Dan's series would have been at
more risk. It kind of still is as I haven't seen him Ack Andrew's
rebase yet?

Thanks,
