[PATCH v2 0/2] tcm/tcm_loop: Add BIDI-COMMAND support

["Nicholas A. Bellinger" <nab@linux-iscsi.org>]

From: Nicholas Bellinger <nab@linux-iscsi.org>

Greetings Boaz and Co,

This is the rebased TCM Core + TCM_Loop module BIDI-COMMAND v2 patch series to
address Boaz's comments about the proper usage of DMA_BIDIRECTIONAL within
TCM Core and TCM_Loop and his other points.  I have already pushed the follow up
patches into lio-core-2.6.git/lio-4.0, and this is a follow up series for Boaz
to add comments w/o the original incorrect DMA_BIDIRECTIONAL usage in the v1 code.

So far this has been tested  with the same custom XDWRITE_READ_10 BSG userspace
code as the v1 patch and things are functioning as expected so far.  I will also
be testing with an BIDI capable sg_raw patch from Doug Gilbert. (Thanks Doug!)

Many thank go to Boaz for sharing his knowledge of BIDI for adding proper support
into TCM Core and TCM_Loop code!

Best,
