Merge branch 'sbp-target-merge' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull sbp-2 (firewire) target mode support from Nicholas Bellinger:
"The FireWire SBP-2 Target is a driver for using an IEEE-1394
connection as a SCSI transport. This module uses the SCSI Target
framework to expose LUNs to other machines attached to a FireWire bus,
in effect acting as a FireWire hard disk similar to FireWire Target
Disk mode on many Apple computers.
Also included are the two drivers/firewire/ patches required by
sbp-target to access fw_request fabric speed needed for mgt_agent
TCODE_WRITE_BLOCK_REQUEST ops, and exporting fw_card kref logic used
when creating/destroying active session references to individual
endpoints.
A credit goes to Chris in being able to get this code up and running
so quickly w/o any target core changes, and special thanks goes out to
Stefan Richter + Clemens Ladisch + Andy Grover for their help in
getting this driver ready for mainline. Also, one of Chris's goals
was to be able to connect sbp-target to a PowerPC based MacOS-X based
client, that he accomplished along the way in this obligatory
screenshot:

Great work Chris + linux-1394 team !!"
