Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy
as correctly noted at bug #12454. Someone can lookup entry with NULL
->owner, thus not pinning enything, and release it later resulting
in module refcount underflow.
We can keep ->owner and supply it at registration time like ->proc_fops
and ->data.
But this leaves ->owner as easy-manipulative field (just one C assignment)
and somebody will forget to unpin previous/pin current module when
switching ->owner. ->proc_fops is declared as "const" which should give
some thoughts.
->read_proc/->write_proc were just fixed to not require ->owner for
protection.
rmmod'ed directories will be empty and return "." and ".." -- no harm.
And directories with tricky enough readdir and lookup shouldn't be modular.
We definitely don't want such modular code.
Removing ->owner will also make PDE smaller.
So, let's nuke it.
Kudos to Jeff Layton for reminding about this, let's say, oversight.

The hardware supports transfers up to a page boundary per buffer.
Currently, we work around that in the DMA code by splitting each
buffer up as we run through the scatterlist. Avoid this by telling
the block layers about the hardware restriction.
Eventually, this will allow us to phase out the splitting code,
but not until the old IDE layer allows us to control the value it
gives to blk_queue_segment_boundary().

driver. I've checked the entire sources, and I don't see any other

sd_revalidate ends up being called several times during device setup.
With this patch we print everything during the first scan. Subsequent

New features are being added to the READ CAPACITY 16 results, so we
want to issue it in preference to READ CAPACITY 10. Unfortunately, some
devices misbehave when they see a READ CAPACITY 16, so we restrict this
command to devices which claim conformance to SPC-3 (aka SBC-2), or claim
they have features which are only reported in the READ CAPACITY 16 data.
The READ CAPACITY 16 command is optional, even for SBC-2 devices, so
we fall back to READ CAPACITY 10 if READ CAPACITY 16 fails.

The sd_read_capacity() function was about 180 lines long and
included a backwards goto and a tricky state variable. Splitting out
read_capacity_10() and read_capacity_16() (about 50 lines each) reduces
sd_read_capacity to about 100 lines and gets rid of the backwards goto
and the state variable. I've tried to avoid any behaviour change with
this patch.

If the iscsi eh fires when the current task is a nop, then
the task->sc pointer is null. fail_all_commands could
then try to do task->sc->device and oops. We actually do
not need to access the curr task in this path, because
if it is a cmd task the fail_command call will handle
this and if it is mgmt task then the flush of the mgmt
queues will handle that.

The qdepth setting was useful when we needed libiscsi to verify
the setting. Now we just need to make sure if older tools
passed in zero then we need to set some default.
So this patch just has us use the sht->cmd_per_lun or if
for LLD does a host per session then we can set it on per
host basis.

We never should hit the lock up that is spit out when
lock dep is on and we logout. But we have been using the

work queue for scanning instead of creating our own,

Memory freeing in iscsi_pool_free() looks wrong to me. Either q->pool
can be NULL and this should be tested before dereferencing it, or it
can't be NULL and it shouldn't be tested at all. As far as I can see,
the only case where q->pool is NULL is on early error in
iscsi_pool_init(). One possible way to fix the bug is thus to not
call iscsi_pool_free() in this case (nothing needs to be freed anyway)
and then we can get rid of the q->pool check.

When LLD supports direct data placement (ddp) for large receive of an scsi
i/o coming into fc_fcp, we call into libfc_function_template's ddp_setup()
to prepare for a ddp of large receive for this read I/O. When I/O is complete,
we call the corresponding ddp_done() to get the length of data ddped as well
as to let LLD do clean up.
fc_fcp_ddp_setup()/fc_fcp_ddp_done() are added to setup and complete a ddped
read I/O described by the given fc_fcp_pkt. They would call into corresponding
ddp_setup/ddp_done implemented by the fcoe layer. Eventually, fcoe layer calls
into LLD's ddp_setup/ddp_done provided through net_device

Make sure for large send is supported by LLD in outgoing FCP data, we are only
sending the lso_max a time in one single large send, since that is what
supported by LLD.

This checks if net_devices supports FCoE offload ops in netdev_ops and it
if it does, then sets up the corresponding flags in the associated fc_lport.
For large send offload, the maximum length supported in one large send is now
described by the added lso_max in fc_lport, which is setup initially from
netdev->gso_max_size.

This adds eth type ETH_P_FCOE for Fibre Channel over Ethernet (FCoE),
consequently, the ETH_P_FCOE from fc_fcoe.h and fcoe skb->protocol
is not set as ETH_P_FCOE.

UNIT_ATTENTION, NOT_READY(02/04/01)
This patch is to add retry for mode select if mode select command is
returned with sense NO_SENSE, UNIT_ATTENTION, ABORTED_COMMAND,
NOT_READY(02/04/01). This patch reorganise the sense keys from if-else
to switch-case format for better maintainability.

The SCSI core calls scsi_proc_hostdir_add() from within
scsi_host_alloc(), but the corresponding scsi_proc_hostdir_rm()
routine is called from within scsi_remove_host(). As a result, if a
host is allocated and then deallocated without ever being registered,
the host's directory in /proc is leaked.
This patch (as1181b) fixes this bug in the SCSI core by moving
scsi_proc_hostdir_rm() into scsi_host_dev_release().

sym53c8xx prints a negotiation message after every check condition.
This can add up to a lot of messages for removable-medium devices
(CD-ROM, tape drives, etc.) that are being polled, since they return
check condition when no medium is present. This patch suppresses the
negotiation message if it would be the same as the last one printed.

sym53c8xx uses a command queue depth of 2 for untagged devices,
without good reason. This _mostly_ seems to work ok, but it has
caused me some subtle problems. For example, I have an application
where one thread sends write commands to a tape drive, and another
thread sends log sense polling commands. With a queue depth of
2, the polling commands end up being starved for long periods of
time while multiple write commands are serviced (this may also be
related to the fact the the sg driver queues commands in LIFO order).
This problem is fixed by changing the queue depth to 1 for untagged
devices. I have tested this change extensively with many different
tape drives, medium changers, and disk drives (disk drives of course
use tagged commands and are therefore unaffected by this patch).

sym_init_device() doesn't check if pci_iomap() fails. It also tries
to map device RAM without first checking FE_RAM.
1) Move some initialization from sym_init_device() to the top of
sym2_probe().
2) Rename sym_init_device() to sym_iomap_device().
3) Call sym_iomap_device() after sym_check_supported() instead of
before so that device->chip.features will be set.
4) Check FE_RAM in sym_iomap_device() before mapping RAM.
5) If sym_iomap_device() cannot map registers, then abort.
6) If sym_iomap_device() cannot map RAM, then fall back to not using
RAM and continue.
7) Remove the check for FE_RAM in sym_attach() since dev->ram_base
is now always set correctly.

During sym2_probe(), sym_init_device() does pci_iomap(), but there is
no corresponding pci_iounmap() if an error occurs before sym_attach()
copies sym_device::s.{ioaddr,ramaddr} to np.
1) Add the sym_iounmap_device() function.
2) Call sym_iounmap_device() if an error occurs between
sym_init_device() and the time sym_attach() allocates np.
3) Make sym_attach() copy sym_device::s.{ioaddr,ramaddr} to np before
calling any function that can fail so that sym_free_resources()
will do the unmap instead of sym_iounmap_device().
Also fixed by this patch:
During sym2_probe(), if sym_check_raid() returns nonzero, then
pci_release_regions() is never called.

This patch fixes two bugs:
1) rmmod sym53c8xx uses shost after freeing it with
scsi_put_host(shost).
2) insmod sym53c8xx doesn't call scsi_put_host(shost) if
scsi_add_host() fails, causing a memory leak on the error path.
