[SCSI] iscsi_tcp: enable sg chaining
The previous patches converted iscsi_tcp to support sg chaining.
This patch sets the proper flags and sets sg_table size to
4096. This allows fs io to be capped at max_sectors, but passthrough
IO to be limited by some other part of the kernel.

[SCSI] libiscsi, iscsi_tcp: iscsi pool cleanup
iscsi_pool_init simplified
iscsi_pool_init currently has a lot of duplicate kfree() calls it does
when some allocation fails. This patch simplifies the code a little by
using iscsi_pool_free to tear down the pool in case of an error.
iscsi_pool_init also returns a copy of the item array to the caller.
Not all callers use this array, so we make it optional.
Instead of allocating a second array and return that, allocate just one
array, of twice the size.
Update users of iscsi_pool_{init,free}
This patch drops the (now useless) second argument to
iscsi_pool_free, and updates all callers.
It also removes the ctask->r2ts array, which was never
used anyway. Since the items argument to iscsi_pool_init
is now optional, we can pass NULL instead.

at llds ctask and is pointed to by iscsi_cmd_task->hdr. Here I add
a hdr_max field pertaining to that storage, and an hdr_len that
accumulates the current use of the pdu-header.
- Add an iscsi_next_hdr() inline which returns the next free space
to write new Header at. Also iscsi_next_hdr() is used to retrieve
the address at which to write the header-digest.
- Add iscsi_add_hdr(length). What the user do is calls iscsi_next_hdr()
for address of the new header, than calls iscsi_add_hdr(length) with
the size of the new header. iscsi_add_hdr() will check if space is
available and update to the new size. length must be padded according
to standard.
- Add 2 padding inline helpers thanks to Olaf. Current patch does not
use them but Following patches will.
Also moved definition of ISCSI_PAD_LEN to iscsi_proto.h which had
PAD_WORD_LEN that was never used anywhere.
- Let iscsi_prep_scsi_cmd_pdu() signal an Error return since now it is

any comments. Changed all places that used sizeof(__u32) or "4" in
connection to a digest.

[SCSI] aacraid: fix driver failure with Dell PowerEdge Expandable RAID Controller 3/Di
As reported in http://bugzilla.kernel.org/show_bug.cgi?id=3D9133 it was
discovered that the PERC line of controllers lacked a key 64 bit
ScatterGather capable SCSI pass-through function. The adapters are still
capable of 64 bit ScatterGather I/O commands, but these two can not be
mixed. This problem was exacerbated by the introduction of the SCSI
Generic access to the DASD physical devices.
The fix for users before this patch is applied is aacraid.dacmode=3D0 on
the kernel command line to disable 64 bit I/O.
The enclosed patch introduces a new adapter quirk and tries to limp
along by enabling pass-through in situations where memory is 32 bit
addressable on 64 bit machines, or disable the pass-through functions
altogether. I expect that the check for 32 bit addressable memory to be
controversial in that it can be incorrect in non-Dell non-Intel systems
that PERC would never be installed under, the alternative is to disable
pass-through in all cases which could be reported as another regression.
Pass-through is used for SCSI Generic access to the physical devices, or
for the management applications to properly function.
In systems where this patch has disabled pass-through because it is
unsupportable in combination with I/O performance, the user can choose
to enable pass-through by turning off dacmode (aacraid.dacmode=3D0) or
limiting the discovered kernel memory (mem=3D4G) with an associated loss
in runtime performance. If we chose instead to turn off 64 bit dacmode
for the adapters with this quirk, then this would be reported as another
regression.

'mid' is a typo. I wanted to do:

Actually there are a lot of endianess warnings, fortunately most of them
harmless. The patch below fixes all of them up (including the ones in

[SCSI] ibmvscsi: requeue while CRQ closed
CRQ send errors that return with H_CLOSED should return with
SCSI_MLQUEUE_HOST_BUSY until firmware alerts the client of a CRQ
transport event. The transport event will either reinitialize and
requeue the requests or fail and return IO with DID_ERROR.
To avoid failing the eh_* functions while re-attaching to the server
adapter this will retry for a period of time while ibmvscsi_send_srp_event
returns SCSI_MLQUEUE_HOST_BUSY.
In ibmvscsi_eh_abort_handler() the loop includes the search of the

again after failing ibmvscsi_send_srp_event. The event could have been
purged if a login was in progress when the function was called.

[SCSI] move single_lun flag from scsi_device to scsi_target
Some SCSI tape medium changers that need the BLIST_SINGLELUN flag have
the medium changer at one LUN and the tape drive at a different LUN.
The inquiry string of the tape drive may be different from that of the
medium changer. In order for single_lun to be effective, every
scsi_device under a given scsi_target must have it set. This means that
there needs to be a blacklist entry for BOTH the medium changer AND the
tape drive, which is impractical because some medium changers may be
paired with a variety of different tape drive models. It makes more
sense to put the single_lun flag in scsi_target instead of scsi_device,
which causes every device at a given target ID to inherit the single_lun
flag from one LUN. This makes it possible to blacklist just the medium
changer and not the tape drive.

[SCSI] 3w-9xxx: fix abysmal write performance on some motherboards
The 3ware 9500S-8 SATA RAID controller exhibits terrible write
performance when PCI memory-write-and-invalidate is disabled. This is
easy to demonstrate by replacing pci_try_set_mwi() in the patch below
with pci_clear_mwi(). My benchmarks show the following:
MWI disabled: 15 MB/s write, 330 MB/s read
MWI enabled: 240 MB/s write, 330 MB/s read
Most motherboards will enable MWI without the driver having to set it
explicitly, so most people probably wouldn't encounter this problem.
For the few motherboards that don't enable it, this patch could give a
16x performance improvement for writing.
This issue does not seem to affect the 9550SX controller, but the patch
doesn't hurt it either. I haven't tested any of the other 3ware
controllers.

[SCSI] add DID_REQUEUE string to scsi_show_result host table
I was working on patches which add new transport error values, when I
noticed that DID_REQUEUE was not in the hostbyte_table. I do not think
there is any way to hit the code path where scsi_show_result is called
and where you return DID_REQUEUE, because DID_REQUEUE causes scsi-ml to
always requeue the command. However, for completeness and because I want
to one day send a patch that tries to add new host bytes values, I am
sending this patch.
