Hi Mathias, This is a follow-up patch for below comment "rebase OGAWA Hirofumi's changes on top of that, and send to usb-linus only" in below discussion thread. https://lkml.org/lkml/2016/12/21/186 I rebased the patch and added unlock-before and lock-after xhci->lock during waiting for the command stopped event. It sits at the same place in your timeout_race_fixes branch.
