[PATCH] kprobe-booster: disable in preemptible kernel
The kprobe-booster's safety check against preemption does not work well
now, because the preemption count has been modified by read_rcu_lock() in
atomic_notifier_call_chain() before we check it. So, I'd like to prevent
boosting kprobe temporarily if the kernel is preemptable.
Now we are searching for the good solution.
