Subject: [PATCH rcu 2/2] rcu-tasks: Clarify the cblist_init_generic() function's pr_info() output
Date: Wed, 10 May 2023 10:10:09 -0700	[thread overview]
Message-ID: <20230510171009.2189185-2-paulmck@kernel.org> (raw)
In-Reply-To: <edff5c4b-e894-4146-8a1d-ae291d01c4fb@paulmck-laptop>

From: Zqiang <qiang1.zhang@intel.com>

This commit uses rtp->name instead of __func__ and outputs the value
of rcu_task_cb_adjust, thus reducing console-log output.
