Bottomley" , linux-scsi@vger.kernel.org, Neerav Parikh , Kiran Patil Content-Type: text/plain; charset="UTF-8" Date: Fri, 29 Jul 2011 09:00:25 +0200 Message-ID: <1311922825.7845.18.camel@edumazet-laptop> Mime-Version: 1.0 X-Mailer: Evolution 2.32.2 Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Since fcoe_percpu_thread_create() creates percpu kthread, it makes sense to use kthread_create_on_node() to get proper NUMA affinity for kthread stack.
