shost->numa_node can be another NUMA node than dev_to_node(dev). Have
you considered using shost->numa_node here ?

It can?  How?

E.g. if the LLD allows the user to specify the value of numa_node and passes that value to scsi_host_alloc_node() (see also http://lkml.org/lkml/2012/10/23/477 for further information).

Just so I'm clear, you're suggesting I use the scsi_device's host
pointer to get to the Scsi_Host, and that *will* be filled in that this
point, right?

As far as I can see the sdev->host pointer is set in scsi_alloc_sdev() and that happens before sd_probe() is invoked.

Bart.
