get_krobe_ctlblk returns a per cpu kprobe control block which holds the state of the current cpu wrt to kprobe. When inserting/removing a kprobe the state of the cpu which replaces the code is changed to KPROBE_SWAP_INST. This however is done when preemption is still enabled. So the state of the current cpu doesn't necessarily reflect the real state. To fix this move the code that changes the state to non-preemptible context.
