Subject: [PATCH v2 4/8] net: mlx5: switch comp_irqs_request() to using for_each_numa_cpu
Date: Wed, 19 Apr 2023 22:19:42 -0700 [thread overview]
Message-ID: <20230420051946.7463-5-yury.norov@gmail.com> (raw)
In-Reply-To: <20230420051946.7463-1-yury.norov@gmail.com>
for_each_numa_cpu() is a more straightforward alternative to
for_each_numa_hop_mask() + for_each_cpu_andnot().
