Subject: [PATCH net 6/9] hv_netvsc: use napi_schedule_irqoff
Date: Thu, 1 Mar 2018 10:27:53 -0800 [thread overview]
Message-ID: <20180301182756.23027-7-sthemmin@microsoft.com> (raw)
In-Reply-To: <20180301182756.23027-1-sthemmin@microsoft.com>
Since the netvsc_channel_cb is already called in interrupt
context from vmbus, there is no need to do irqsave/restore.
