This code appears to be more trouble than it's worth, considering that
no normal users reload drivers. So, we comment it for now. It is not
removed outright for the benefit of hackers (that is, myself).

This patch fixes a few problems with ub and cleans up a couple of things:
- Bump UB_MAX_REQ_SG, this allows to burn CDs
- Drop initialization of urb.transfer_flags,
now that URB_UNLINK_ASYNC is gone
- Add forgotten processing of stalls at GetMaxLUN
- Remove a few more P3-tagged printks whose time has come
- Correct comment about ZIP-100

Don't count additional writes created inside the packet driver to satisfy the

Add SCSI host and device info not elsewhere available to /proc/scsi/cciss/*
Namely, connect cciss device instance with scsi host number, and give scsi
host number, bus, target, lun, devicetype, and 8-byte cciss LUNID for each
tapedrive/medium changer attached to a controller
For instance:
# cat /proc/scsi/cciss/2
cciss0: SCSI host: 2

This patch adds support for "One Button Disaster Recovery" devices to the
cciss driver. (OBDR devices are tape drives which can pretend to be cd-rom
devices temporarily. Once booted the device can be reverted to a tape drive
and data recovery operations can be automatically begun.)
This is an enhancement request by a vendor/partner working on One Button
Disaster Recovery.

The CCISS driver seems to loose track of DMA mappings created by it's
fill_cmd() routine. Neither callers of this routine are extracting the DMA
address created in order to do the unmap.
Instead, they simply try to unmap 0x0. It's easy to see this problem on an
x86_64 system when using the "swiotlb=force" boot option. In this case, the
driver is leaking resources of the swiotlb and not causing a sync of the
bounce buffer.

This patch changes the way we complete commands. In the old method when we
got a completion we searched our command list from the top until we find it.
This method uses a tag associated with each command (not SCSI command tagging)
to index us directly to the completed command. This helps performance.

This patch removes a couple of functions dealing with configuration and
replaces them with new functions. This implementation fixes some bugs
associated with the ACUXE. It also allows a logical volume to be removed from
the middle without deleting all volumes behind it.
If a user has 5 logical volumes and decides he wants to reconfigure volume
number 3, he can now do that without removing volumes 4 & 5 first. This code
has been tested in our labs against all application software.

This patch adds a flag called busy_initializing. If there are multiple
controllers in a server AND the HP agents are running it's possible the agents
may try to poll a card that is still initializing if the driver is removed and
then added again.

This patch adds new PCI and subsystem ID's that finally made the spec. It
also include a name change for one controller. I know there's a lot of
duplicat names but the fw folks wanted this for the different implementations.
Even though the same ASIC is used it may be embedded on some platforms,
standup card in others, and a mezzanine in other servers.

The reference count fix merged isn't fully bug free. It doesn't leak
now, but instead it crashes due to looking at freed memory. So for now,
lets reverse the change and I'll fix it for real next week.

Use msleep() or msleep_interruptible() [as appropriate] instead of
schedule_timeout() to gurantee the task delays as expected. As a result
changed the units of the timeout variable from jiffies to msecs.
