The device limit of 128 tape drives was established in 2003 as a significant increase from the 8 tape drives allowed previously. We have seen many Linux sites that, between a large number of tape drives and multipathing, are discovering more than 128 devices and are running into problems. This patch set cleans up some st code that made increasing the number of drives costly, then actually increases the maximum number from 128 to 2^17 devices (based on the current code). This patch set is based off of the scsi git tree.
