There was a logic fault in scsi_io_completion() where zero transfer
commands that complete successfully were sent to the block layer as
not up to date. This patch removes the if (good_bytes > 0) gate
around the successful completion, since zero transfer commands do have
good_bytes == 0.

I got a NULL derefrence in cdev_del+1 when called from sg_remove. By looking at
the code of sg_add, sg_alloc and sg_remove (all in drivers/scsi/sg.c) I found
out that sg_add is calling sg_alloc but if it fails afterwards it does not
deallocate the space that was allocated in sg_alloc and the redundant entry has
NULL in cdev. When sg_remove is being called, it tries to perform cdev_del to
this NULL cdev and fails.

This patch adds or modifies the transport class functions
used to notify userspace of session state events.
We modify the session addition up event and add a destruction event
to notify userspace of session creation, relogin and destruction.
And we modify the conn error event to be sent by broadcast
since multiple listeners may want to listen for it.

So the drivers do not use the channel numbers, but some do
use the target numbers. We were just adding some goofy
variable that just increases for the target nr. This is useless
for software iscsi because it is always zero. And for qla4xxx
the target nr is actually the index of the target/session
in its FW or FLASH tables. We needed to expose this to userspace
so apps could access those numbers so this patch just adds the
target nr to the iscsi session creation functions. This way
when qla4xxx's Hw thinks a session is at target nr 4
in its hw, it is exposed as that number in sysfs.

qla4xxx is initialized in two steps like other HW drivers.
It allocates the host, sets up the HW, then adds the host.
For iscsi part of HW setup is setting up persistent iscsi
sessions. At that time, the interupts are off and the driver
is not completely set up so we just want to allocate them.
We do not want to add them to sysfs and expose them to userspace
because userspace could try to do lots of fun things with them
like scanning and at that time the driver is not ready.
So this patch breakes up the session creation like other
functions that use the driver model in two the alloc
and add parts. When the driver is ready, it can then add
the sessions and userspace can begin using them.
This also fixes a bug in the addition error patch where
we forgot to do a get on the session.

I do not remember what I was thinking when we added the channel
as a argument to the session create function. It was probably
due to too much cut and paste work from the FC transport class.
The channel is meaningless for iscsi drivers so this patch drops
its usage everywhere in the iscsi related code.

iscsi_tcp and iser cannot be rmmod from the kernel when sessions
are running because session removal is driven from userspace. For
those modules we get a module reference when a session is
created then drop it when the session is removed.
For qla4xxx, they can jsut remove the sessions from the pci remove
function like normal HW drivers, so this patch moves the module
reference from the transport class functions shared by all
drivers to the libiscsi functions only used be software iscsi
modules.

Reduce duplication in the software iscsi_transport modules by
adding a libiscsi function to handle the common grunt work.
This also has the drivers return specifc -EXXX values for different
errors so userspace can finally handle them in a sane way.
Also just pass the sysfs buffers to the drivers so HW iscsi can
get/set its string values, like targetname, and initiatorname.

Add target discovery event. We may have a setup where the iscsi traffic
is on a different netowrk than the other network traffic. In this case

If a device gets offlined as a result of the Inquiry sent
during scanning, the following oops can occur. After the
disk gets put into the SDEV_OFFLINE state, the error handler
sends back the failed inquiry, which wakes the thread doing
the scan. This starts a race between the scanning thread
freeing the scsi device and the error handler calling
scsi_run_host_queues to restart the host. Since the disk
is in the SDEV_OFFLINE state, scsi_device_get will still
work, which results in __scsi_iterate_devices getting
a reference to the scsi disk when it shouldn't.
The following execution thread causes the oops:
CPU 0 (scan) CPU 1 (eh)
---------------------------------------------------------
scsi_probe_and_add_lun
....
scsi_eh_offline_sdevs
scsi_eh_flush_done_q
scsi_destroy_sdev
scsi_device_dev_release
scsi_restart_operations
scsi_run_host_queues
__scsi_iterate_devices
get_device
scsi_device_dev_release_usercontext
scsi_run_queue
<---OOPS--->
The patch fixes this by changing the state of the sdev to SDEV_DEL
before doing the final put_device, which should prevent the race
from occurring.
Original oops follows:

This is a resend of a patch I generated in response to an email sent
by Ruben Faelens <parasietje@gmail.com>. His original email to
linux-scsi requested a method in which he could spin down a scsi disk
when not in use and have the kernel automatically spin it back up when
an I/O was generated to the disk. The infrastructure to automatically
spin a disk up has been in the scsi error handler for some time now,
but it is not enabled by default. This patch adds an sd sysfs attribute
which allows userspace to enable this behavior.

Original post was incorrect as it didn't realize that we already had
a self-referenc due to device_initialize(), and we were really only
missing the put on our own reference. This was hidden by the other bug
which had the midlayer reusing stargets after they were already free,
which was doing too many puts on our rport.
Updating FC transport for:
- Add put in fc_rport_final_delete(), to release the rport.
Prior, we were leaving the rport with a reference, thus the shost
with references, etc. If the driver was unloaded, shosts and rports
remained, along with work threads, etc
- Fix fc_rport_create failure path - too many put's on parent
- Add commenting to easily track ref taking.

In a prior posting to linux-scsi on the fc transport and workq
deadlocks, we noted a second error that did not have a patch:
http://marc.theaimsgroup.com/?l=linux-scsi&m=114467847711383&w=2
- There's a deadlock where scsi_remove_target() has to sit behind
scsi_scan_target() due to contention over the scan_lock().
Subsequently we posted a request for comments about the deadlock:
http://marc.theaimsgroup.com/?l=linux-scsi&m=114469358829500&w=2
This posting resolves the second error. Here's what we now understand,
and are implementing:
If the lldd deletes the rport while a scan is active, the sdev's queue
is blocked which stops the issuing of commands associated with the scan.
At this point, the scan stalls, and does so with the shost->scan_mutex held.
If, at this point, if any scan or delete request is made on the host, it
will stall waiting for the scan_mutex.
For the FC transport, we queue all delete work to a single workq.
So, things worked fine when competing with the scan, as long as the
target blocking the scan was the same target at the top of our delete
workq, as the delete workq routine always unblocked just prior to
requesting the delete. Unfortunately, if the top of our delete workq
was for a different target, we deadlock. Additionally, if the target
blocking scan returned, we were unblocking it in the scan workq routine,
which really won't execute until the existing stalled scan workq
completes (e.g. we're re-scheduling it while it is in the midst of its
execution).
This patch moves the unblock out of the workq routines and moves it to
the context that is scheduling the work. This ensures that at some point,
we will unblock the target that is blocking scan. Please note, however,
that the deadlock condition may still occur while it waits for the
transport to timeout an unblock on a target. Worst case, this is bounded
by the transport dev_loss_tmo (default: 30 seconds).
Finally, Michael Reed deserves the credit for the bulk of this patch,
analysis, and it's testing. Thank you for your help.
Note: The request for comments statements about the gross-ness of the
scan_mutex still stand.

Some SATA controllers embedded in ATI IXPs seem to have broken
SATA_IRQ bit in their bmdma2 registers which is always stuck at 1.
This makes the driver believe that there has been a hotplug event and

commands.
