Is this what you were thinking when > adding the bio sense code? I mean doing things like sg io and dm-multipath HW handler's manual failover with bios instead of requests could simplify those things, but I am guessing bios were not meant to handle some of the lower level details like SCSI things. Or maybe they are or should be done in a more generic way? - : send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
