Subject: [PATCH] rcu/rcutorture: Eliminate variable n_rcu_torture_boost_rterror
Date: Tue, 17 Jan 2023 13:53:10 +0800 [thread overview]
Message-ID: <20230117055310.3408-1-zbestahu@gmail.com> (raw)
From: Yue Hu <huyue2@coolpad.com>
After commit 8b700983de82 ("sched: Remove sched_set_*() return value"),
this variable is not used anymore. So eliminate it entirely.
