Subject: [PATCH] workqueue: Simplify pool_allowed_cpus()
Date: Thu, 11 Jul 2024 16:38:31 +0800 [thread overview]
Message-ID: <20240711083831.4273-1-jiangshanlai@gmail.com> (raw)
From: Lai Jiangshan <jiangshan.ljs@antgroup.com>
For cpu worker pools, attrs->affn_strict is true; attrs->__pod_cpumask
and attrs->cpumask are the same. Skip the pool->cpu test
in pool_allowed_cpus() and use pool->attrs->__pod_cpumask.
