    SubjectRE: [Patch 6/7] megaraid_sas: adds tasklet for cmd completion
    Date
    From
    Hello Christoph,

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

    Regards,
    Sumant

    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?
