I've added Linus to this, so he's aware of what's going on, since if
I do merge Eric's latest tree, Linus will see duplicate commits from
me and I don't wish to have one of Linus' responses to that. ;)

The general rule is that once you've asked someone to pull your tree,
that's it, the commits are cast in stone.  It doesn't matter who you
ask to pull your tree.
