This is somewhat pendatic, but it helps me review patches if we keep things together.
Since we're no longer doing the memcpy in this function, can we please move the cmd->pos += len
to the location where we actually do the memcpy.

I'm willing to be told to get over it if other reviewers don't like that approach, but if no one cares
please move it.

Do the above here instead.
