Subject: [patch,v2 02/10] scsi: make __scsi_alloc_queue numa-aware
Date: Fri,  2 Nov 2012 17:45:55 -0400	[thread overview]
Message-ID: <1351892763-21325-3-git-send-email-jmoyer@redhat.com> (raw)
In-Reply-To: <1351892763-21325-1-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.
