This is a single fix for the queue refcounting oops we were debugging just before 3.0-rc1 was released. Jens is still working on the DEAD queue guard bit.
The patch is available here:
master.kernel.org:/pub/scm/linux/kernel/git/jejb/scsi-rc-fixes-2.6.git
The short changelog is:

The diffstat is:

And the full patch is below.
