I get the feeling that some of the bugs we are seeing is because we have enabled CONFIG_PREEMPT_BKL. I remember looking at the code when it came out and thinking it was too scary to enable, so I never did in my own vanilla kernels.
yes, we should keep it enabled - it's the default upstream and we havent had PREEMPT_BKL related bugs for a really long time.
in fact i had more !PREEMPT_BKL bugs than PREEMPT_BKL bugs. (BKL spinlock recursion for example)
well, PREEMPT_BKL is not the default - my points remain nevertheless.
