Last year at $DAYJOB we were having issues with slow fetches/pulls/pushes. We added some additional trace2 regions which helped us narrow down the issue to some server-side negotiation problems. We've been carrying these patches downstream ever since, but they might be useful to others as well. Changes in V2: * Added a new patch to implement trace2_printf() for event targets. * Move some fetch trace regions deeper in the call stack to simplify control flow. * Move some push trace regions deeper in the call stack to target the actual slow functions, and to not tie tracing to whether or not sideband communication is used.
