Subject: [PATCH 04/10] sched_ext: idle: use assign_cpu() to update the idle cpumask
Date: Fri, 20 Dec 2024 16:11:36 +0100	[thread overview]
Message-ID: <20241220154107.287478-5-arighi@nvidia.com> (raw)
In-Reply-To: <20241220154107.287478-1-arighi@nvidia.com>

Use the assign_cpu() helper to set or clear the CPU in the idle mask,
based on the idle condition.
