Subject: [PATCH] KVM: x86/mmu: remove unnecessary flush_workqueue()
Date: Fri, 1 Apr 2022 08:35:30 +0000 [thread overview]
Message-ID: <20220401083530.2407703-1-lv.ruyi@zte.com.cn> (raw)
From: Lv Ruyi <lv.ruyi@zte.com.cn>
All work currently pending will be done first by calling destroy_workqueue,
so there is unnecessary to flush it explicitly.
Reported-by: Zeal Robot <zealci@zte.com.cn>
