Subject: [PATCH 0/1] xhci: Fix race related to abort operation

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.

(git://git.kernel.org/pub/scm/linux/kernel/git/mnyman/xhci.git timeout_race_fixes)

Best regards,
Lu Baolu
