Show the current binary tape driver and mode options is sysfs. A file
(options) is created in each directory in /sys/class/scsi_tape. The files
contain masks showing the options. The mask bit definitions are the same as
used when setting the options using the MTSETDRVBUFFER function in the
MTIOCTOP ioctl (defined in include/linux/mtio.h). For example:
> cat /sys/class/scsi_tape/nst0/options
0x00000d07

Add new option MT_ST_SILI to enable setting the SILI bit in reads in variable
block mode. If SILI is set, reading a block shorter than the byte count does
not result in CHECK CONDITION. The length of the block is determined using the
residual count from the HBA. Avoiding the REQUEST SENSE command for every
block speeds up some real applications considerably.

- add arcmsr_enable_eoi_mode()and readl(reg->iop2drv_doorbell_reg) in
arcmsr_handle_hbb_isr() on adapter Type B in case of the doorbell
interrupt clearance is cached
- add conditional declaration for arcmsr_pci_error_detected() and

- check if the sg list member number exceeds arcmsr default limit in
arcmsr_build_ccb()
- change the returned value type of arcmsr_build_ccb()from "void" to
"int" returns FAILED in arcmsr_queue_command()
- modify arcmsr_drain_donequeue() to ignore unknown command and let
kernel process command timeout. This could handle IO request violating
maximum segments, i.e. Linux XFS over DM-CRYPT. Thanks to Milan Broz's

The cards being added are supported in a limited sense already through
family matching, but we needed to add some functionality to the driver
to expose selectively the physical drives. These Physical drives are
specifically marked to not be part of any array and thus are declared
JBODs (Just a Bunch Of Drives) for generic SCSI access.
We report that this is the second patch in a set of two, but merely
depends on the stand-alone functionality of the first patch which adds
in that case the ability to report a driver feature flag via sysfs. We
leverage that functionality by reporting that this driver now supports
this new JBOD feature for the controller so that the array management
applications may react accordingly and guide the user as they manage
the controller.

Device Initiated Power Management, which is defined
in SATA 2.5 can be enabled for disks which support it.
This patch enables DIPM when the user sets the link
power management policy to "min_power".
Additionally, libata drivers can define a function
(enable_pm) that will perform hardware specific actions to
enable whatever power management policy the user set up
for Host Initiated Power management (HIPM).
This power management policy will be activated after all
disks have been enumerated and intialized. Drivers should
also define disable_pm, which will turn off link power
management, but not change link power management policy.
Documentation/scsi/link_power_management_policy.txt has additional
information.

This patch provides support for FC virtual ports based on NPIV.
For information on the interfaces and design, please read the
Documentation/scsi/scsi_fc_transport.txt file enclosed within
the patch.
The RFC was originally posted here:
http://marc.info/?l=linux-scsi&m=117226959918393&w=2
Changes from the initial RFC:
- Bug fix: needed a transport_class_unregister() for the vport class
- Create a symlink to the vport in the shost device if it is not the
parent of the vport.
- Made symbolic name writable so it can be set after creation
- Made the temporary fc_vport_identifiers struct private to the
transport.
- Deleted the vport_id field from the vport. I couldn't find any good
use for it (and symname is a good replacement).
- Made the vport_state and vport_last_state "private" attributes.
Added the fc_vport_set_state() helper function to manage state
transitions
- Updated vport_create() to allow a vport to be created in a disabled
state.
- Added INITIALIZING and FAILED vport states
- Added VPCERR_xxx defines for errors to be returned from vport_create()
- Created a Documentation/scsi/scsi_fc_transport.txt file that describes
the interfaces and expected LLDD behaviors.

When abort failed, the driver gets reset handleer called. In the reset
handler, driver calls 'scsi_done()' callback for same SCSI command packet
(struct scsi_cmnd) multiple times if there are multiple SCSI command packet
in the pend_list. More over, if there are entry in the pend_lsit with
IOCTL packet associated, the driver returns it to wrong free_list so that,
in turn, the driver could end up with 'NULL pointer dereference..' during
I/O command building with incorrect resource.

This patch updates the documentation for aic7xxx and aic79xx with fixes
from the adaptec driver.

This patch defines a new template to represent each type of
controllers (identified by the processor used). The template has
members that is set with appropriate values during driver
initialisation. This change is done to support new controllers with
minimal change to existing code. In future, for a new controller
support, a template will be declared and its members initialised
appropriately.

This patch adds Documentation/scsi/scs_eh.txt. I've chosen plain
text over DocBook as most other scsi docs are in plain text and it's
more accessible.

scsi_add_host is the proper place to set the device, but people copy
the scsi_set_device usage from older drivers again and again.
note that this leaves some legacy drivers like qlogicisp/qlogicfc
without pci association in sysfs, but they're scheduled to go away soon
anyway.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
