With reasonably recent git (>= 2.5), another option worth considering is
using worktrees:

  cd /src/GIT/linux
  git remote add --no-tags net-next git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next.git
  git branch --track net-next net-next/master
  git worktree add ../net-next net-next

It works well for me, the only limitation to keep in mind is that you
cannot have the same branch checked out in two different worktrees at
the same time.
