Hey Ricky, I noticed this CL in my incoming reviews, but didn't get an email
about it. If it's ready for review, you'll want to use the "Publish+Mail
Comments" link to mail out a CL.

Anyway, patch set 1 LGTM, but I think you'll need to sync and resolve some
conflicts first.

Oops, didn't realize I needed to publish+mail, thanks for catching this,
mdempsky!
