SCSI for-linus on 20141220 

This is a much shorter set of patches that were on the go but didn't make it
 in to the early pull request for the merge window.  It's really a set of bug
 fixes plus some final cleanup work on the new tag queue API.

This is a host adapter simulator that can simulate multiple hosts
each with multiple dummy SCSI devices (disks). It defaults to one
host adapter with one dummy SCSI disk. Each dummy disk uses kernel
RAM as storage (i.e. it is a ramdisk). To save space when multiple
dummy disks are simulated, they share the same kernel RAM for
their storage. See <http://sg.danny.cz/sg/sdebug26.html> for more
information. This driver is primarily of use to those testing the
SCSI and block subsystems. If unsure, say N.
This pseudo driver simulates one or more hosts (SCSI initiators),
each with one or more targets, each with one or more logical units.
Defaults to one of each, creating a small RAM disk device. Many
parameters found in the /sys/bus/pseudo/drivers/scsi_debug
directory can be tweaked at run time.
See <http://sg.danny.cz/sg/sdebug26.html> for more information.
Mainly used for testing and best as a module. If unsure, say N.
