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)" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (51 commits) target: Fix percpu_ref_put race in transport_lun_remove_cmd target/iscsi: Fix network portal creation race target: Report bad sector in sense data for DIF errors iscsi-target: Convert gfp_t parameter to task state bitmask iscsi-target: Fix connection reset hang with percpu_ida_alloc percpu_ida: Make percpu_ida_alloc + callers accept task state bitmask iscsi-target: Pre-allocate more tags to avoid ack starvation qla2xxx: Configure NPIV fc_vport via tcm_qla2xxx_npiv_make_lport qla2xxx: Enhancements to enable NPIV support for QLOGIC ISPs with TCM/LIO. qla2xxx: Fix scsi_host leak on qlt_lport_register callback failure IB/isert: pass scatterlist instead of cmd to fast_reg_mr routine IB/isert: Move fastreg descriptor creation to a function IB/isert: Avoid frwr notation, user fastreg IB/isert: seperate connection protection domains and dma MRs tcm_loop: Enable DIF/DIX modes in SCSI host LLD target/rd: Add DIF protection into rd_execute_rw target/rd: Add support for protection SGL setup + release target/rd: Refactor rd_build_device_space + rd_release_device_space target/file: Add DIF protection support to fd_execute_rw target/file: Add DIF protection init/format support ...
