    Subject[PATCH 4.14 212/496] hv_netvsc: use napi_schedule_irqoff
    Date
    4.14-stable review patch.  If anyone has any objections, please let me know.

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

    From: Stephen Hemminger <stephen@networkplumber.org>

    [ Upstream commit 68633edaef655ce94e51088ecef5dd4e1d2f6f34 ]

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