[GIT PULL] target: Updates for v3.2-rc1 (round one)

[Nicholas A. Bellinger]

Hi Linus,

The following is the first round of target updates for v3.2-rc1.  It's
available directly from kernel.org here:

  git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git for-next

What can I say...?  Christoph really outdid himself this round with a
long list of cleanups culminating with the conversion to push the core
completion path out of transport_processing_thread() and into a separate
target workqueue.   There are still a number of performance improvements
in the works, most of which at this point will end up being v3.3 items.
Also included are a handful of bugfixes reported by various folks that
are marked for stable@xxxxxxxxxx, and other various improvements +
removal of legacy code.

The bulk of this series has been posted for review in the last weeks
here:

[PATCH 00/37] target: Updates for v3.2-rc1 (round one)
http://marc.info/?l=linux-scsi&m=131855299419466&w=2

Unfortunately this code has only gotten minimal linux-next testing as
the target-pending.git tree did not return to kernel.org until last
week.  I've been able to verify it does not conflict with linux-next
from 20111014, and has been getting some testing in lio-core.git and I'm
content enough for an merge into v3.2-rc1.

For the second round of v3.2-rc1 changes, a new ib_srpt module will be
merged once Roland is happy with the recent review cleanups.  There is
still some outstanding non-critical breakage with last rounds conversion
to use errno.h in certain areas that still needs to be addressed, as
well as a active I/O shutdown refactoring that Iâm also targeting for
v3.2-rc1.

Thank you,
