Red Hat Bugzilla – Bug 506981
[QLogic 5.4 bug] qla4xxx: Testing updates, 4 fixes.
Last modified: 2009-09-03 09:47:42 EDT
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
- 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.
