Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending

Pull scsi-target changes from Nicholas Bellinger:
 "There has been lots of work in existing code in a number of areas this
  past cycle.  The major highlights have been:

   * Removal of transport_do_task_sg_chain() from core + fabrics
     (Roland)
   * target-core: Removal of se_task abstraction from target-core and
     enforce hw_max_sectors for pSCSI backends (hch)
   * Re-factoring of iscsi-target tx immediate/response queues (agrover)
   * Conversion of iscsi-target back to using target core memory
     allocation logic (agrover)

  We've had one last minute iscsi-target patch go into for-next to
  address a nasty regression bug related to the target core allocation
  logic conversion from agrover that is not included in friday's
  linux-next build, but has been included in this series.

  On the new fabric module code front for-3.5, here is a brief status
  update for the three currently in flight this round:

   * usb-gadget target driver:

  Sebastian Siewior's driver for supporting usb-gadget target mode
  operation.  This will be going out as a separate PULL request from
  target-pending/usb-target-merge with subsystem maintainer ACKs.  There
  is one minor target-core patch in this series required to function.

   * sbp ieee-1394/firewire target driver:

  Chris Boot's driver for supportting the Serial Block Protocol (SBP)
  across IEEE-1394 Firewire hardware.  This will be going out as a
  separate PULL request from target-pending/sbp-target-merge with two
  additional drivers/firewire/ patches w/ subsystem maintainer ACKs.

   * qla2xxx LLD target mode infrastructure changes + tcm_qla2xxx:

  The Qlogic >= 24xx series HW target mode LLD infrastructure patch-set
  and tcm_qla2xxx fabric driver.  Support for FC target mode using
  qla2xxx LLD code has been officially submitted by Qlogic to James
  below, and is currently outstanding but not yet merged into
  scsi.git/for-next..

    [PATCH 00/22] qla2xxx: Updates for scsi "misc" branch
    http://www.spinics.net/lists/linux-scsi/msg59350.html

  Note there are *zero* direct dependencies upon this for-next series
  for the qla2xxx LLD target + tcm_qla2xxx patches submitted above, and
  over the last days the target mode team has been tracking down an
  tcm_qla2xxx specific active I/O shutdown bug that appears to now be
  almost squashed for 3.5-rc-fixes."
