[GIT PULL] target updates for v3.9-rc1 (round two)

[Nicholas A. Bellinger]

Hi Linus,

Here are the remaining target-pending patches for v3.9-rc1.  Please go
ahead and pull from:

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

The most important one here is the immediate queue starvation regression
fix for iscsi-target, which addresses a bug that's effecting v3.5+
kernels under heavy sustained READ only workloads.  Thanks alot to
Benjamin Estrabaud for helping to track this down!

Also included is a pSCSI exception bugfix from Asias, along with a
handful of other minor changes.  Both bugfixes are CC'ed to stable.

Thank you,

Asias He (4):
  target: Add __exit annotation for module_exit functions
  target/pscsi: Drop unnecessary NULL assignment to bio->bi_next
  target/pscsi: Fix page increment
  target/pscsi: Rename sg_num to nr_vecs in pscsi_get_bio()

[GIT PULL] target updates for v3.9-rc1

[Nicholas A. Bellinger]

Hi Linus,

Here are the target pending updates for v3.9-rc1 code.  Please go ahead
and pull from:

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

The highlights in this series include:

- Improve sg_table lookup scalability in RAMDISK_MCP (martin)
- Add device attribute to expose config name for INQUIRY model (tregaron)
- Convert tcm_vhost to use lock-less list for cmd completion (asias)
- Add tcm_vhost support for multiple target's per endpoint (asias)
- Add tcm_vhost support for multiple queues per vhost (asias)
- Add missing mapped_lun bounds checking during make_mappedlun
  setup in generic fabric configfs code (jan engelhardt + nab)
- Enforce individual iscsi-target network portal export once per
  TargetName endpoint (grover + nab)
- Add WRITE_SAME w/ UNMAP=0 emulation to FILEIO backend (nab)

Things have been mostly quiet this round, with majority of the work
being done on the iser-target WIP driver + associated iscsi-target
refactoring patches currently in flight for v3.10 code.

At this point there is one patch series left outstanding from Asias to
add support for UNMAP + WRITE_SAME w/ UNMAP=1 to FILEIO awaiting
feedback from hch & Co, that will likely be included in a post v3.9-rc1
PULL request if there are no objections.

Also, there is a regression bug recently reported off-list that seems to
be effecting v3.5 and v3.6 kernels with MSFT iSCSI initiators that is
still being tracked down.  No word if this effects >= v3.7 just yet, but
if so there will likely another PULL request coming your way..

Thank you,

--nab
