4fe74b1cb0 [SCSI] virtio-scsi: SCSI driver for QEMU based virtual machines
The virtio-scsi HBA is the basis of an alternative storage stack
for QEMU-based virtual machines (including KVM).  Compared to
virtio-blk it is more scalable, because it supports many LUNs
on a single PCI slot), more powerful (it more easily supports
passthrough of host devices to the guest) and more easily
extensible (new SCSI features implemented by QEMU should not
require updating the driver in the guest).

5a4f934e65 [SCSI] hpsa: add some older controllers to the kdump blacklist
Some other older controllers also do have problems to perform a kdump.
Adding controllers to this list means that the driver will signal
this non-ability via a resettable flag correctly.
The unsupported list was created after a consultation with HP.

Permanent target failures are non-retryable and should be classified as
TARGET_ERROR; otherwise dm-multipath will retry an IO request that will
always fail at the target.

sense 0x20, 0x21, 0x24 or 0x26 represents a permanent TARGET_ERROR.

0083208473 [SCSI] libfc: Handle discovery failure during ctlr link down
While we wait for GPN_FT response, if the ctlr link goes down, the stack
generates a completion for GPN_FT with error FC_EXCH_CLOSED, and reports a
discovery error. Discovery is not retried in this case, and rightly so.
However, the 'pending' flag stays set, which does not allow subsequent
discovery to succeed as GPN_FT will never be issued. Fix it by clearing the
pending flag when the discovery fails due to GPN_FT failure.

d4042e9c84 [SCSI] libfc: Fix panic in fc_exch_recv
Adding and removing the host into the zone causes this panic.

BUG: unable to handle kernel NULL pointer dereference at 00000000000000a0

During fc_exch_reset, the active exchanges are aborted and the exch is deleted.
As part of processing ABTS response, due to 'ep' being NULL, any access to ep in
fc_exch_recv_bls() causes this panic. Fixed to access 'ep' only if non-NULL.

1a8ef414d9 [SCSI] fcoe: Remove reference counting on 'stuct fcoe_interface'
The reference counting was necessary on these instances
because it was possible for NPIV ports to be destroyed
after the N_Port. A previous patch ensures that all NPIV
ports are destroyed before the N_Port making the need to
track references on the interface unnecessary.

ccefd23ed2 [SCSI] fcoe: Do not switch context in vport_delete callback
Currently all port deletion is routed though the FCoE
workqueue (fcoe_wq). When fc_remove_host is called on
an N_Port (for example, from fcoe_destroy) the vports
are queued into a FC Transport workqueue. fc_remove_host
flushes that queue and each vport is passed to fcoe's
fcoe_vport_destroy, which simply queues the associated
fcoe_ports for later deletion. This queue cannot be
flushed within the N_Ports destroy path because of
circular locking issues. The result is that the NPIV
ports are destroyed after the N_Port, which is reverse
of how they are created.

This quirk causes fcoe to keep references on the
fcoe_interface shared by each of these ports (N_Port
and NPIV). Changing the ordering such that NPIV ports
are destroyed before the N_Port will allow us to remove
reference counting on the fcoe_interface instances.

This patch simply allows fcoe_vport_destory to destroy
NPIV ports without deferring them to a workqueue context.
This ensures that when fc_remove_host is called the
NPIV ports will be destroyed first before the N_Port and
allows reference counting on the fcoe's fcoe_interface
to be remove in a later patch.

6f68794c92 [SCSI] fcoe: Rename out_nomod label to out_putmod
The label implies that it should be called when
there is 'nomod.' I read that to mean that the
module reference 'get' failed. However, it's only
called when the module reference 'get' succeeded.

I think it makes more sense to name the label,
'out_putmod' since it should be called when we
need to 'put' the module reference taken in the
routine before returning.

aa61556fa3 [SCSI] qla2xxx: Return blank sysfs string on initial get thermal failure.
When thermal temperature initially fails, return a blank string to the
sysfs interface.  This fixes the initial display of 0.00 followed by
subsequent display of blank line; the initial 0.00 should have not
displayed for cards that do not support thermal temperature.
