Subject: [PATCH 06/15] tick: No need to clear ts->next_tick again
Date: Thu, 1 Feb 2024 00:11:11 +0100 [thread overview]
Message-ID: <20240131231120.12006-7-frederic@kernel.org> (raw)
In-Reply-To: <20240131231120.12006-1-frederic@kernel.org>
The tick sched structure is already cleared from
tick_cancel_sched_timer(), so there is no need to clear that field
again.
