Hi Linus,
This the first update for v4.1 target core development series code that
has been a WIP over the spring and summer months within the LIO upstream
tree, and contains the rebased + squashed series for a mainline v3.1-rc1
merge to re-sync drivers/target/ with the latest lio-core-2.6.git code.
This includes the significant efforts driven by Andy Grover and
Christoph Hellwig to convert target core to use native struct
scatterlist from original pre .24 SGL link logic in target core (struct
se_mem), including the complete conversion of target control CDB
emulation to use a single page SGL, and the necessary rebased bugfixes
to address the various items of breakage encountered along the way..
Note this includes target core changes required by iscsi-target v4.1
code to use a streamlined method of I/O submission for SW target fabrics
as desired for v3.1 by Christoph and Andy. It also contains Roland's
spinlock IRQ usage fixes to address interrupt context usage with
tcm_qla2xxx HW code currently in flight for v3.2, and even includes a
full CONFIG_DYNAMIC_DEBUG conversion from Andy for drivers/target/,
along with many more general cleanups, simplifications and improvements
to reduce the mainline code by > 1500 LOC!
Please go ahead and pull from the following:

The 'target-pending.git/for-linus-core' branch has been made against the
following upstream HEAD:
commit 02f8c6aee8df3cdc935e9bdd4f2d020306035dbe
Author: Linus Torvalds <torvalds@xxxxxxxxxxxxxxxxxxxx>
Date: Thu Jul 21 19:17:23 2011 -0700
Linux 3.0
Finally, I want to mention that Andy did win this round in the target
patch count rankings with a pre-squashed count of 66 patches, together
with a large number of Reviewed-by assists from Christoph. A exceeding
large thank you everyone who has contributed, and especially to those
who have been driving v4.1 code development.
Thank you!
