Hi, All of the infrastructure is available to allocate a request_queue on a particular numa node, but it isn't being utilized at all. Wire up the sd driver to allocate the request_queue on the HBA's local numa node. This is a request for comments and testing (I've built and booted it, nothing more). I believe that this should be a performance win, but I have no numbers to back it up as yet. Suggestions for workloads to test are welcome.
