Hi Linus,

Here are the target-pending updates for v4.12-rc1. Please go ahead and
pull from:

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

Things where alot more calm than previously expected. It's primarily
fixes in various areas, with most of the new functionality centering
around TCMU backend driver work that Xiubo Li has been driving.

Here's the summary on the feature side:

- Make T10-PI verify configurable for emulated (FILEIO + RD) backends
(Dmitry Monakhov)
- Allow target-core/TCMU pass-through to use in-kernel SPC-PR logic
(Bryant Ly + MNC)
- Add TCMU support for growing ring buffer size (Xiubo Li + MNC)
- Add TCMU support for global block data pool (Xiubo Li + MNC)

and on the bug-fix side:

- Fix COMPARE_AND_WRITE non GOOD status handling for READ phase
failures (Gary Guo + nab)
- Fix iscsi-target hang with explicitly changing per NodeACL
CmdSN number depth with concurrent login driven session
reinstatement. (Gary Guo + nab)
- Fix ibmvscsis fabric driver ABORT task handling (Bryant Ly)
- Fix target-core/FILEIO zero length handling (Bart Van Assche)

Also, there was an OOPs introduced with the WRITE_VERIFY changes that I
ended up reverting at the last minute, because as not unusual Bart and I
could not agree on the fix in time for -rc1. Since it's specific to a
conformance test, it's been reverted for now.

There is a separate patch in the queue to address the underlying control
CDB write overflow regression in >= v4.3 separate from the WRITE_VERIFY
revert here, that will be pushed post -rc1.

Thank you,

--nab
