Subject: Can srcu_read_lock() be called from interrupt context?
Date: Mon, 2 Nov 2015 17:56:56 -0800 [thread overview]
Message-ID: <20151103015656.GA10358@jnakajim-build> (raw)
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?
Thanks
