James you have missed a very serious fix to scsi_lib.
  http://www.spinics.net/lists/linux-scsi/msg41125.html

In Fedora12, if there is an iscsi device in the system, as a normal user
I can run a cooked up, push bidi commands via bsg program that can easily
crash the Kernel. It must be plugged. (Regardless if the target is not
bidi the command can error, it does not matter)

The fix itself is a one liner no brainer. Just use before you free.

Also needed by stable
