Subject: [PATCH v2 2/6] net: thunderx: Use napi_schedule_irqoff()
Date: Thu, 11 Feb 2016 21:50:22 +0530 [thread overview]
Message-ID: <1455207626-35488-3-git-send-email-sunil.kovvuri@gmail.com> (raw)
In-Reply-To: <1455207626-35488-1-git-send-email-sunil.kovvuri@gmail.com>
From: Sunil Goutham <sgoutham@cavium.com>
napi_schedule is being called from hard irq context, hence
switch to napi_schedule_irqoff which avoids unneeded call
to local_irq_save and local_irq_restore.
