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

Pull SCSI target updates from Nicholas Bellinger:
 "The highlights this round include:

  - add support for SCSI Referrals (Hannes)
  - add support for T10 DIF into target core (nab + mkp)
  - add support for T10 DIF emulation in FILEIO + RAMDISK backends (Sagi + nab)
  - add support for T10 DIF -> bio_integrity passthrough in IBLOCK backend (nab)
  - prep changes to iser-target for >= v3.15 T10 DIF support (Sagi)
  - add support for qla2xxx N_Port ID Virtualization - NPIV (Saurav + Quinn)
  - allow percpu_ida_alloc() to receive task state bitmask (Kent)
  - fix >= v3.12 iscsi-target session reset hung task regression (nab)
  - fix >= v3.13 percpu_ref se_lun->lun_ref_active race (nab)
  - fix a long-standing network portal creation race (Andy)"
