Subject: [PATCH 5/6] timers/nohz: Remove middle-function __tick_nohz_idle_stop_tick()
Date: Fri, 10 Feb 2023 15:09:16 +0100 [thread overview]
Message-ID: <20230210140917.279062-6-frederic@kernel.org> (raw)
In-Reply-To: <20230210140917.279062-1-frederic@kernel.org>
There is no need for the __tick_nohz_idle_stop_tick() function between
tick_nohz_idle_stop_tick() and its implementation. Remove that
unnecessary step.
