See http://www.infradead.org/rpr.html Switch to the ->device_configure method instead of ->slave_configure and update the block limits on the passed in queue_limits instead of using the per-limit accessors. Note that mpi3mr also updates the limits from an event handler that iterates all SCSI devices. This is also updated to use the queue_limits, but the complete locking of this path probably means it already is completely broken and needs a proper audit.
