If anyone has any objections, please let me know. ------------------ From: Johannes Thumshirn commit 2bcbc81421c511ef117cadcf0bee9c4340e68db0 upstream. The qla1280 driver sets the scsi_host_template's can_queue field to 0xfffff which results in an allocation failure when allocating the block layer tags for the driver's queues. This was introduced with the change for host wide tags in commit 64d513ac31b - "scsi: use host wide tags by default". Reduce can_queue to MAX_OUTSTANDING_COMMANDS (512) to solve the allocation error.
