The S/390 DASD driver could conceivably make use of generic block layer (or higher-up) multi-path support. (We have multi-path support on a lower level, the channel subsystem, but this helps only with reliability / failover. Using multi-path support on a higher level for performance reasons would be helpful in certain scenarios.)
