Subject: [PATCH v3 5/8] net: mlx5: switch comp_irqs_request() to using for_each_numa_cpu
Date: Sun, 30 Apr 2023 10:18:06 -0700 [thread overview]
Message-ID: <20230430171809.124686-6-yury.norov@gmail.com> (raw)
In-Reply-To: <20230430171809.124686-1-yury.norov@gmail.com>
for_each_numa_online_cpu() is a more straightforward alternative to
for_each_numa_hop_mask() + for_each_cpu_andnot().
