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

Pull scsi target updates from Nicholas Bellinger:
 "Things have been calm for the most part with no new fabric drivers in
  flight for v3.7 (we're up to eight now !), so this update is primarily
  focused on addressing a few long-standing items within target-core and
  iscsi-target fabric code.

  The highlights include:

   - target: Simplify fabric sense data length handling (roland)
   - qla2xxx: Fix endianness of task management response code (roland)
   - target: fix truncation of mode data, support zero allocation length
     (paolo)
   - target: Properly support zero-length commands in normal processing
     path (paolo)
   - iscsi-target: Correctly set 0xffffffff field within ISCSI_OP_REJECT
     PDU (ronnie + nab)
   - iscsi-target: Add explicit set of cache_dynamic_acls=1 for TPG
     demo-mode (ronnie + nab)
   - target/file: Re-enable optional fd_buffered_io=1 operation (nab +
     hch)
   - iscsi-target: Add MaxXmitDataSegmenthLength forr target ->
     initiator MDRSL declaration (nab)
   - target: Add target_submit_cmd_map_sgls for SGL fabric memory
     passthrough (nab + hch)
   - tcm_loop: Convert I/O path to use target_submit_cmd_map_sgls (hch +
     nab)
   - tcm_vhost: Convert I/O path to use target_submit_cmd_map_sgls (nab
     + hch)

  The last series for adding a new target_submit_cmd_map_sgls() fabric
  caller (as requested by hch) that accepts pre-allocated SGL memory
  (using existing logic), along with converting tcm_loop + tcm_vhost has
  only been in -next for the last days, but has gotten enough review
  +testing and is clear enough a mechanical change that I think it's
  reasonable to merge for -rc1 code.

  Thanks again to everyone who contributed this round! Extra special
  thanks to Roland (PureStorage) for tracking down the qla2xxx target
  TMR response code endian issue, and to Paolo (Redhat) for resolving
  the long standing zero-length CDB issues within target-core between
  virtual and pSCSI backends."
