ebd1f645bd [SCSI] scsi_dh_alua: Decrease retry interval
The alua device handler starts the first retry after 10 seconds,
and increases it times 10 for each round.
This leads to an unnecessary delay. This patch modifies it to
start after one second, and increase by a factor of two.

cfde3fa166 [SCSI] scsi_dh_alua: Fix Erroneous TPG ID check
For Target Portal Group IDs occupying the full 2 bytes in the
RTPG response, the following group_id check in the alua_rtpg
routine always fails in scsi_dh_alua.c:

if (h->group_id == (ucp[2] << 8) + ucp[3]) {

This causes the ALUA handler to wrongly identify the AAS of
a specified device as well as incorrectly interpreting the
supported AAS of the target as seen by the following entries
in the /var/log/messages:

"alua: port group 3ea state A supports tousna"
"alua: port group 3e9 state A supports tousna"

This is because 'ucp' is wrongly declared in alua_rtpg as
a character pointer instead of an unsigned character pointer.

6c3633d08a [SCSI] scsi_dh: Implement match callback function
Some device handler types are not tied to the vendor/model
but rather to a specific capability. Eg ALUA is supported
if the 'TPGS' setting in the standard inquiry is set.
This patch implements a 'match' callback for device handler
which supersedes the original vendor/model lookup and
implements the callback for the ALUA handler.

ac81c6a832 [SCSI] libsas: fix sas_queuecommand return values
->queuecommand must return either 0, or one of the SCSI_MLQUEUE_* return
values.  Non-transient errors are indicated by setting cmd->result before
calling ->scsi_done and returning 0.  Fix libsas to adhere to this calling
convention.  Note that the DID_ERROR for returns from the low-level driver
might not be correct for all cases, but it's the best we can do with
the current layering in libsas.  I also suspect that the pre-existing
handling of -SAS_QUEUE_FULL should really be SCSI_MLQUEUE_HOST_BUSY, but
I'll leave that for a separate change.

a72c5e5eb7 [SCSI] genhd: add a new attribute "alias" in gendisk
This patch allows the user to set an "alias" of the disk via sysfs interface.

This patch only adds a new attribute "alias" in gendisk structure.
To show the alias instead of the device name in kernel messages,
we need to revise printk messages and use alias_name() in them.

Example:
(current) printk("disk name is %s\n", disk->disk_name);
(new)     printk("disk name is %s\n", alias_name(disk));

Users can use alphabets, numbers, '-' and '_' in "alias" attribute. A disk can
have an "alias" which length is up to 255 bytes. This attribute is write-once.

76e4e12ff2 [SCSI] scsi scan: don't fail scans when host is in recovery
The problem is that if we are doing a scsi scan then the device goes
into recovery then we will wait for the recovery to complete. It waits
because scsi-ml will send inquiries or report luns and the queueing code
will have been blocked due to the host not being ready. However, if we
are in recovery and then a scan is started the scan will silently fail
and some devices will not be added.

It is easy to hit the problem where devices do not show up with
FC where we are doing tests that disrupt the target controllers.
When the controller is disruprted (reboot, or setting firmware, etc),
and we cause the dev loss tmo to fire then devices will be removed
Then when the problem has been fixed, the rport will be scanned and
devices should be added back. But if we cause another disruption before
scanning has started then devices will not get added back. If the problem
is not started until the scan is started then the devices will be added
back.

This patch fixes that problem by not failing scans when the host
is in recovery. We will let scsi-ml send the IO and let the queueing
and scsi error handling deal with it like is done if we went into
recovery while scanning.

For recovery cases where the host is being torn down then with the
patch we will still fail the scan since there is not point in scanning.

  the RN bit and ERR bit of the SLIPORT_STATUS register. If none of them

  immediately without getting into the wait for RDY bits on the SLIPORT_STATUS
  register.
- Remove the driver check on dev->is_physfn before proceed to perform the
  PHYSDEV_CONTROL register write, and let the PCI function's privilege
  setting and driver handling of PHYSDEV_CONTROL register write failure to
  handle the reset-ability through the SLI port.
- Added key to ctlreg_write to prevent unauthorized or unexpected write to
  the control register.
- Change return to EACCES for sysfs access that are failed because hba_reset

- Swap all values that come from the firmware image on little endian systems.
  Created a new bf_get_be macro that does the same as the bf_get_le macro but

- Moved the incrementing of temp_offset after the copy
  fixed the write object loop to use temp_offset to figure out where the end
  of the image is instead of offset.
- Added the necessary codes for properly bringing the driver instance offline
  and then trying to bring the port back online with the PCI function IP reset.
  If it fails to bring the SLI port back online, it will fall through to
  bringing the SLI port to HBA error offline.

dfcf777581 [SCSI] Fix out of spec CD-ROM problem with media change
Some CD-ROMs fail to report a media change correctly.  The specific
one for this patch simply fails to respond to commands, then gives a
UNIT ATTENTION after being reset which returns ASC/ASCQ 28/00.  This
is out of spec behaviour, but add a check in the eat CC/UA on reset
path to catch this case so the CD-ROM will function somewhat properly.
