Subject: [PATCH tip/core/rcu 08/12] rcu: Make nocb_nobypass_lim_per_jiffy static
Date: Wed, 3 Mar 2021 16:23:07 -0800 [thread overview]
Message-ID: <20210304002311.23655-8-paulmck@kernel.org> (raw)
In-Reply-To: <20210304002225.GA23492@paulmck-ThinkPad-P72>
From: Jiapeng Chong <jiapeng.chong@linux.alibaba.com>
RCU triggerse the following sparse warning:
kernel/rcu/tree_plugin.h:1497:5: warning: symbol
'nocb_nobypass_lim_per_jiffy' was not declared. Should it be static?
This commit therefore makes this variable static.
