Subject: Re: [RFC PATCH net-next 00/11] net: remove disable_irq() from ->ndo_poll_controller
Date: Tue, 09 Dec 2014 21:44:33 -0500 (EST) [thread overview]
Message-ID: <20141209.214433.7463087833083181.davem@davemloft.net> (raw)
In-Reply-To: <1418135842-21389-1-git-send-email-sd@queasysnail.net>
Adding a new spinlock to every interrupt service routine is
simply a non-starter.
You will certainly have to find a way to fix this in a way
that doesn't involve adding any new overhead to the normal
operational paths of these drivers.
Thanks.
