The ipr driver can hang if it encounters enough PCI errors
to trigger the permanent error handler. The driver will attempt
to initiate a "bringdown" of the adapter and fail all pending
ops back. However, this bringdown is unlike any other bringdown
of the adapter in the code as the driver. In this code path we
end up failing back ops with allow_cmds still set to 1. This results
in some commands, the HCAM commands in particular, getting immediately
re-issued to the adapter on the done call, which results in
an infinite loop in ipr_fail_all_ops. Fix this by setting allow_cmds
to zero in this path.

scsi timeout on two or more devices may cause extremely long execution
time for user applications because SDEV_OFFLINE state is changed to
SDEV_RUNNING state during scsi error recovery procedures triggered by
a bus reset or a host reset of scsi LLD, and scsi timeout can happens
on the same devices many times.

This happens because scsi_internal_device_unblock() changes device's
state to SDEV_RUNNING even if a device in other states than SDEV_BLOCK,
while the following two transitions are required in this function.

  SDEV_BLOCK -> SDEV_RUNNING
  SDEV_CREATED_BLOCK -> SDEV_CREATED

Otherwise, it returns -EINVAL.

Make the sym53c8xx_2 driver slave_alloc/destroy less unsafe. References
to the destroyed LCB are cleared from the target structure (instead of
leaving a dangling pointer), and when the last LCB for the target is
destroyed the reference to the upper layer target data is cleared. The
host lock is used to prevent a race with the interrupt handler. Also
user commands are prevented for targets with all LCBs destroyed.

Changing a lun's queue depth (/sys/block/sdX/device/queue_depth)
isn't sticky when the device is connected via a QLogic fibre
channel adapter.

The QLogic qla2xxx fibre channel driver dynamically adjusts a
lun's queue depth.  If a user has a specific need to limit the
number of commands issued to a lun (say a tape drive, or a shared
raid where the total commands issued to all luns is limited at
the controller level, for example) and writes a limiting value to
/sys/block/sdXX/device/queue_depth, the qla2xxx driver will
silently and gradually increase the queue depth back to the
driver limit of ql2xmaxqdepth.  While reducing this value (module
parameter) or increasing the interval between ramp ups
(ql2xqfullrampup) offers the potential for a work around it would
be better to have the option of just disabling the dynamic
adjustment of queue depth.

This patch implements an "off switch" as a module parameter.

The short-circuit to skip the non-applicable 'full-login-lip'
