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.
let me double-correct myself: PREEMPT_BKL is indeed default enabled on SMP:
config PREEMPT_BKL bool "Preempt The Big Kernel Lock" depends on SMP || PREEMPT default y help
so basically everyone who tests SMP kernels has it.
