Subject: [GIT PULL] sbp-target merge for v3.5-rc1

Hi Linus,

Here is the next pull request for Chris Boot's new Serial Block Protocol
(sbp) target driver for IEEE-1394 (FireWire) hardware.  This code also
has been in linux-next for a number of weeks, and is ready for an
initial merge.

Please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git sbp-target-merge

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 !!
