[PATCH 4.14 212/496] hv_netvsc: use napi_schedule_irqoff

From: Greg Kroah-Hartman
Date: Mon May 28 2018 - 09:07:04 EST


4.14-stable review patch. If anyone has any objections, please let me know.

------------------

From: Stephen Hemminger <stephen@xxxxxxxxxxxxxxxxxx>

[ Upstream commit 68633edaef655ce94e51088ecef5dd4e1d2f6f34 ]

Since the netvsc_channel_cb is already called in interrupt
context from vmbus, there is no need to do irqsave/restore.
