Description Marcus Barrow 2009-06-19 16:31:13 UTC
Testing at QLogic has found 4 more issues. These patches address these significant problems.

 - Extended Sense Data Errors UPDATE

    The previous fix used a scratchpad area that was already in use. Provide appropriate storage for this
     information


 - Code Cleanup Removed residual from overrun debug print

    Correct the information provided by these prints so as not to provide mis-leading information.
    Residual is not valid for over runs.


 - Fixed NULL pointer dereference in eh_device reset

    eh_device_reset may be called from scsi error handler or sg_reset, etc.
    When called from sg_reset, there will not be an associated srb.
    Also removed DEAD code (marker_needed variable in ha struct)


 - Removed unused hiwater code

    This frees up the number available IOCBs.  Eliminates unnecessary
    eh_ escalations due to inability to obtain IOCB pkt for marker.


Changes have been tested at QLogic.
