Subject: [RFC][PATCH 00/13] firewire-sbp-target: FireWire SBP-2 SCSI target

Hi folks,

Well after lots of work I have a working and generally (at least I think)
sensible starting point for the FireWire target. It appears to work fine in all
the configurations I've tested it against, including Linux and Mac OS X
initiators.

This is not production ready code, and not ready for merging IMO. I know my
locking (or more the lack of it) leaves something to be desired, and I know my
use of atomics and memory barriers is wrong too. Performance is also a bit
meagre and I'm sure it can be improved substantially - I already have some
ideas for things that can be improved.

For testing, I use:

GUID=5254000b8f01e6f6
DIR_ID=abcdef

modprobe firewire-sbp-target
mkdir /sys/kernel/config/target/sbp
mkdir /sys/kernel/config/target/sbp/$GUID
mkdir /sys/kernel/config/target/sbp/$GUID/tpgt_1
mkdir /sys/kernel/config/target/sbp/$GUID/tpgt_1/lun/lun_0
ln -s /sys/kernel/config/target/core/iblock_0/sbptest /sys/kernel/config/target/sbp/$GUID/tpgt_1/lun/lun_0/sbptest
echo $DIR_ID > /sys/kernel/config/target/sbp/$GUID/tpgt_1/directory_id
echo 1 > /sys/kernel/config/target/sbp/$GUID/tpgt_1/enable

Setting the directory_id is optional and something I have only just added, but
it appears to work as planned.

Any and all comments much appreciated.

Thanks,
Chris
