Yeah, I have this problem very often when I push to the ext4 tree on master.kernel.org. Apparently the push/pull logic isn't smart about objects are found via objects/info/alterntaes, so it will needlessly transfer objects that it doesn't need to. What I do to deal with this problem is I'll manually log into master.kernel.org, and then use the command "git-update-ref refs/heads/origin 19af35546de68c872dcb687613e0902a602cb20e", and then go back and do the push/pull. Once there is a head which points to the latest from Linus, then the push/pull logic is smart and will only download the few commitments that aren't in the local git repository and aren't found in a shared repository. Annoying, but as long as you have shell access on the machine with the destination repository, you can work around it. - Ted
