This just introduced an unbounded latency and will fail PREEMPT_RT.

Hi Steve,

Sorry about that!

If I understand correctly, there is absolutely no need to explicitly
disable preemption in this context. I will use: rcu_read_lock() and
rcu_read_unlock(), respectively, which will then be suitable for the
preemptible RCU implementation.


Kind regards,
