shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the=
patch applied to the branch. This will indicate if there was any rebasing needed to apply to the stable branch. If there were code changes for rebasi= ng
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
