The patches fix the races.

But I saw a failure I didn't saw before during stress test [1].
It is hard to say if it is related to your patches :
- we test on a older kernel version and I backported usbaudio from 3.7 with your
patches
- the start of the trace is missing and it is difficult to understand the list
corruption.
