Subject: [PATCH net-next v3] net/mlx5: Simplify cpumask operations in comp_irq_request_sf()
Date: Fri, 5 Jun 2026 18:17:56 +0800 [thread overview]
Message-ID: <20260605101756.91275-1-fushuai.wang@linux.dev> (raw)
From: Fushuai Wang <wangfushuai@baidu.com>
Combine cpumask_copy() and cpumask_andnot() into a single
cpumask_andnot() since the function can take cpu_online_mask
directly as the source.
