| title: | PATCH 1 6 USB BKL Remove lock kernel in us |
|
From: Andi Kleen <ak@xxxxxxxxxxxxxxx
The code this is attempting to lock against does not use the BKL,
so its not needed.
Most likely this code is still broken/racy (Al Viro also thinks so),
but removing the BKL should not make it worse than before.
