    [SCSI] scsi_error: add target reset handler · 30bd7df8
    Mike Christie authored
    The problem is that serveral drivers are sending a target reset from the
    device reset handler, and if we have multiple devices a target reset gets
    sent for each device when only one would be sufficient. And if we do a target
    reset it affects all the commands on the target so the device reset handler
    code only cleaning up one devices's commands makes programming the driver a
    little more difficult than it should be.
    
    This patch adds a target reset handler, which drivers can use to send
    a target reset. If successful it cleans up the commands for a devices
    accessed through that starget.
