2010-09-16T15:48:48+00:00

Fix two bugs in the VPD page wrapper:

    - Don't return failure if the user asked for page 0

    - The end of buffer check failed to account for the page header size
      and consequently didn't work

[SCSI] sd: fix medium-removal bug

2010-09-07T15:31:54+00:00

Commit 409f3499a2cfcd1e9c2857c53af7fcce069f027f (scsi/sd: remove big
kernel lock) introduced a bug in the sd_release routine.  Medium
removal should be allowed when the number of open file references
drops to 0, not when it becomes non-zero.

This patch (as1414) adjusts the test to fix the bug.

[SCSI] qla2xxx: Cover UNDERRUN case where SCSI status is set.

2010-09-05T18:18:31+00:00

Currently, if target sets the SCSI Status (with Check condition)
and there is no FCP residual bit set then driver  does not check
for dropped frame.  This could lead to data corruption.

if there is a mbx waiting.

[SCSI] qla2xxx: Reset seconds_since_last_heartbeat correctly.

2010-09-05T18:18:28+00:00

The seconds_since_last_heartbeat should be checked for consecutive
heartbeat checks. Currently it could happen that seconds_since_last_heartbeat
gets set to max (2 seconds) for non-consecutive heartbeat checks.
