[GIT PULL] target updates for v3.16-rc1

["Nicholas A. Bellinger" <nab@linux-iscsi.org>]

Hello Linus,

Here are the target-pending updates for v3.16-rc1 code.  Please go ahead
and pull from:

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

Note that you'll need to 'thread the needle' this time around, as there
are no less than four different merge conflicts / build breakages that
have been reported in linux-next (srf CC'ed) over the last weeks.

The first is with virtio-scsi between what has been merged in scsi.git
for "virtio_scsi: use cmd_size", and the "virtio-scsi: Enable DIF/DIX
modes in SCSI host LLD" below.  (Adding Paolo + hch CC')

http://marc.info/?l=linux-kernel&m=140083605208042&w=2

The second is with qla2xxx between what has been merged in scsi.git
for "qla2xxx: T10-Dif: add T10-PI support", and the "qla2xxx: Convert to
percpu_ida session tag pre-allocation" below.  (Adding Quinn CC')

http://marc.info/?l=linux-next&m=140109133803347&w=2

The third is with vhost-scsi between what has been merged in vhost.git
for "vhost: move acked_features to VQs", and the "vhost/scsi: Enable T10
PI IOV -> SGL memory mapping" below.  (Adding MST CC')
 
http://marc.info/?l=linux-next&m=140237354814532&w=2

And the last is with virtio-scsi between what has been merged in
virtio.git for "virtio_scsi: don't call virtqueue_add_sgs(... GFP_NOIO)
holding spinlock.", and the "virtio-scsi: Enable DIF/DIX modes in SCSI
host LLD" below.  (Adding Rusty CC')

http://marc.info/?l=linux-next&m=140254666208366&w=2

All the conflicts aside, the highlights this round include:

  - Add support for T10 PI pass-through between vhost-scsi + virtio-scsi
    (MST + Paolo + MKP + nab)
  - Add support for T10 PI in qla2xxx target mode (Quinn + MKP + hch + nab,
    merged through scsi.git)
  - Add support for percpu-ida pre-allocation in qla2xxx target code
    (Quinn + nab)
  - A number of iser-target fixes related to hardening the network portal
    shutdown path (Sagi + Slava)
  - Fix response length residual handling for a number of control CDBs
    (Roland + Christophe V.)
  - Various iscsi RFC conformance fixes in the CHAP authentication path
    (Tejas and Calsoft folks + nab)
  - Return TASK_SET_FULL status for tcm_fc(FCoE) DataIn + Response failures
    (Vasu + Jun + nab)
  - Fix long-standing ABORT_TASK + session reset hang (nab)
  - Convert iser-initiator + iser-target to include T10 bytes into EDTL
    (Sagi + Or + MKP + Mike Christie)
  - Fix NULL pointer dereference regression related to XCOPY introduced
    in v3.15 + CC'ed to v3.12.y (nab)

Thank you,
