This Patch will provide more details of the devices such as slot number,
enclosure logical id, enclosure level & connector name in the following
scenarios,
- When end device is added in the topology,
- When the end device is removed from the setup,
- When the SCSI mid layer issues TASK ABORT/ DEVICE RESET/ TARGET RESET during
error handling,
- When any command to the device fails with Sense key Hardware error or Medium
error or Unit Attention,
- When firmware returns device error or device not ready status for the end
device,
- When a Predicted fault is detected on an end device.
This information can be used by the user to identify the location of the
desired drive in the topology.
Driver will get these information by reading the sas device page0.

During hot-plugging of a disk(having a flaky link), the disk addition
stops and any further disk addition or removal doesn't happen on that
controller.
This is because, when driver receives DELAY_NOT_RESPONDING event for a disk
while it is undergoing addition at the SCSI Transport layer, the driver
would block the I/O to that disk resulting in a deadlock. i.e the disk
addition work couldn't be completed at the SCSI Transport Layer as it
can't send any I/Os (such as Inquiry, Report LUNs etc) to the disk as
I/Os are blocked to this drive. Also any subsequent device removal
(TARGET_NOT_RESPONDING) or link update(RC_PHY_CHANGED) event couldn't be
processed as they are in the queue to get processed after disk addition
event.
Description of Change:
Don't block the drive when drive addition is under the control of SML.
So that SML won't be blocked of issuing the device dicovery commands
(such as Inquiry, Report LUNs etc).

card gets into READY or Operational state.
Driver initialization fails if driver tries to send IOC facts request message
when the IOC is in reset or in a fault state.
This patch will make sure that
1.Driver to send IOC facts request message only if HBA is in operational or
ready state.
2.If IOC is in fault state, a diagnostic reset would be issued.
3.If IOC is in reset state then driver will wait for 10 seconds to exit out
of reset state. If the HBA continues to be in reset state, then the HBA
wouldn't be claimed by the driver.

support
In this patch, increased the number of MSIX vector support for SAS3 C0 HBAs to
up-to 96.
Following are changes that are done in this patch
1. This feature is enabled only for SAS3 C0 and higher revision cards and also
only when reply post free queue count is greater than 8.
2. To support this feature 12 SupplementalReplyPostHostIndex system interfaces
are used. MSI-X index numbered from 0 to 7 use the first
SupplementalReplyPostHostIndex system interface to update its corresponding
ReplyPostHostIndex values, MSI-X index numbered from 8 to 15 will use the
second SupplementalReplyPostHostIndex system interface and so on. These 12
SuppementalReplyPostHostIndex system interfaces address are saved in the array
replyPostRegisterIndex[].
3. As each SupplementalReplyPostHostIndex register supports 8 MSI-X
vectors. So MSIxIndex field in these register must contain a value between 0
and 7.
4. After processing the reply descriptors from a reply post free queues then
update the new reply post host index value in ReplyPostHostIndex field and
(msix_index mod 8) value in MSIxIndex field of SupplementalReplyPostHostIndex
register. The Address of this SupplementalReplyPostHostIndex register is
retrived from (msix_index/8)th entry of replyPostRegisterIndex[] array.

Introduce support for enhanced I/O error handling.
A device state is added to track 3 possible states of the device:
Normal - the device is operating normally and is fully operational
Limbo - the device is in a reset/recovery scenario and its operational
status is paused
Failed/terminating - the device has either failed to be reset/recovered
or is being terminated (removed); it is no longer
operational
All operations are allowed when the device is operating normally. When the
device transitions to limbo state, I/O must be paused. To help accomplish
this, a wait queue is introduced where existing and new threads can wait
until the device is no longer in limbo. When coming out of limbo, threads
need to check the state and error out gracefully when encountering the
failed state. When the device transitions to the failed/terminating state,
normal operations are no longer allowed. Only specially designated
operations related to graceful cleanup are permitted.

scsi_error: should not get sense for timeout IO in scsi error handler
When an IO timeout occurs, the IO will be aborted in
scsi_abort_command() and SCSI_EH_ABORT_SCHEDULED will be set. Because
of that, the SCSI_EH_CANCEL_CMD will be clear in scsi_eh_scmd_add().
So when scsi error handler starts, it will get sense for this
timeout IO and the scmd of the IO request will be reused. In that
case, the scmd may be double released when racing with io_done(),
which will result in crash.
SO SCSI_EH_ABORT_SCHEDULED should also be checked when getting sense.
The bug maybe reproduced when the link between host and disk is
unstable.
