Subject: [patch,v3 02/10] scsi: make __scsi_alloc_queue numa-aware
Date: Fri, 9 Nov 2012 14:17:59 -0500 [thread overview]
Message-ID: <1352488687-19935-3-git-send-email-jmoyer@redhat.com> (raw)
In-Reply-To: <1352488687-19935-1-git-send-email-jmoyer@redhat.com>
Pass the numa node id set in the Scsi_Host on to blk_init_queue_node
in order to keep all allocations local to the numa node the device is
closest to.
