[SCSI] qla2xxx: Correct handling of AENs postings for vports.

2008-05-30T17:20:57+00:00

Initialize all proper structure members in order to support
work-list vport processing.  This code also properly acquires the
correct (physical hardware_lock) lock during work submission.

[SCSI] qla2xxx: Revert "qla2xxx: Use proper HA during asynchronous event handling."

2008-05-30T17:20:43+00:00

This reverts commit bd2a1846b2313e32d0270151a31a6b8335384a20.
The original (prior to the reverted commit) code was correct.
Additionally, the vp_idx should be checked during MBA_PORT_UPDATE
in order for proper handling to take place for a given vport.

[SCSI] ibmvscsi: Non SCSI error status fixup

2008-05-27T16:10:57+00:00

Some versions of the Virtual I/O Server on Power
return 0x99 in the non-SCSI error status field as success,
rather than 0. This fixes the ibmvscsi driver to treat this
response as success.

The problem is caused by:

commit b0ed43360fdca227048d88a08290365cb681c1a8

    [SCSI] add scsi_host and scsi_target to scsi_bus

which added scsi_bus_type to the struct scsi_target device.  This
causes both the scsi_device and scsi_target to fire scsi_bus_uevents.
However, the actualy scsi_bus_uevent() call assumes blindly that it's
a struct scsi_device.  Check for this and return immediately if it
isn't.

SCSI: fix race in device_create

2008-05-20T20:31:56+00:00

There is a race from when a device is created with device_create() and
then the drvdata is set with a call to dev_set_drvdata() in which a
sysfs file could be open, yet the drvdata will be NULL, causing all
sorts of bad things to happen.

This patch fixes the problem by using the new function,
device_create_drvdata().  It fixes the problem in all of the scsi
drivers that need it.
