Subject: [PATCH 0/4] Userspace Passthrough backstore for LIO

Hi all,

Here is version three of the userspace passthrough backstore code I've
been working on. I think it's ready to be considered for upstream.

If you are wondering what this is, patch 3 is documentation that
should explain, at both a high- and low-level.

There are other pieces needed for this to work properly -- changes to
targetcli and rtslib to easily configure the new backstore type, plus
the user code that hooks up to the passthrough. I've written some code
to do this, called tcmu-runner
(https://github.com/agrover/tcmu-runner) but the userspace development
naturally is hindered until the kernel code is accepted :)

Changes since version 2:
* Incorporate doc improvements from Richard W. M. Jones
* Correct off-by-1 error in tcmu_get_blocks
* execute_rw must be set in the sbc_ops passed to sbc_parse_cdb

Thanks -- Andy
