Subject: [PATCH net-next] net: napi_watchdog() can use napi_schedule_irqoff()
Date: Tue, 21 Feb 2017 08:20:56 -0800	[thread overview]
Message-ID: <1487694056.9415.27.camel@edumazet-glaptop3.roam.corp.google.com> (raw)

From: Eric Dumazet <edumazet@google.com>

hrtimer handlers run with masked hard IRQ, we can therefore
use napi_schedule_irqoff()
