Hi nab and all,
Here are some miscellaneous cleanups I've been working on, with the goal
to get back to core-allocated buffers (done), and streamline the iscsi
handle_cmd code so it can use target_submit_cmd() (made progress but not done
yet.)
There are also many other patches unrelated to the above goal in here,
primarily shooting for less complex and more readable code, but not changing
what it functionally does.
Code compiled and smoketested.
Regards -- Andy
