See http://www.infradead.org/rpr.html This is a version of ->slave_configure that also takes a queue_limits structure that the caller applies, and thus allows drivers to reconfigure the queue using the atomic queue limits API. In the long run it should also replace ->slave_configure entirely as there is no need to have two different methods here, and the slave name in addition to being politically charged also has no basis in the SCSI standards or the kernel code.

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.

See http://www.infradead.org/rpr.html Switch to the ->device_configure method instead of ->slave_alloc and update the block limits on the passed in queue_limits instead of using the per-limit accessors. Note that uas was the only driver setting these size limits from ->slave_alloc and not ->slave_configure and this makes it match everyone else.
