Hi, Paul I have a question to the srcu_read_lock(). Can it be invoked on interrupt context? According to http://lxr.free-electrons.com/source/kernel/rcu/srcu.c#L292 it can only be called from process context, but according to http://lxr.free-electrons.com/source/include/linux/srcu.h#L213 seems it's ok from irq context only if it matches with the srcu_read_unlock. Can you please give some hints?
