With implementation of tasklet in the driver we see a performance increase of about 8%, so we decided to go with it.

Why would you need this? The normal scsi command completion is offloaded to the SCSI softirq ASAP so I don't see any point for those. Do you see too much time spent in completion of the internal commands? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
