    For those that aren't aware, the BKL (big kernel lock) hasn't caused any issues except purist angst for a very long time now. All of the performance critical kernel code was fixed to use fine grained locking years ago. This change is just to satisfy the people who are offended by the architectural ugliness of the BKL. In terms of performance and everything else that matters, the removal of the BKL has absolutely no impact.
