Default is off. This tasklet usage doesn't quite look right. What a tasklet does is defer processing until after all interrupts have completed. It's commonly used for aggregation, which is why scsi_done simply queues for the block softirq (tasklet). However, for mvsas, I don't see any benefit to defering the work to a tasklet. Additionally, for the non MSI case, doesn't the interrupt, which is level triggered, fail to deassert because we haven't cleared any registers?
