Subject: [PATCH] mm/vmscan: don't disable irq again when count pgrefill for memcg
Date: Wed, 24 Apr 2019 16:11:34 +0800 [thread overview]
Message-ID: <1556093494-30798-1-git-send-email-laoar.shao@gmail.com> (raw)
We can use __count_memcg_events directly because this callsite is alreay
protected by spin_lock_irq.
