Also included are a few DIF related fixes, a qla2xxx fix (Cc'ed to stable) from Greg W., and vhost/scsi protocol version related fix from Venkatesh. Also just a heads up that a series to address a number of issues with iser-target active I/O reset/shutdown is still being tested, and will be included in a separate -rc6 PULL request" * git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: vhost/scsi: Check LUN structure byte 0 is set to 1, per spec qla2xxx: Fix kernel panic on selective retransmission request Target/sbc: Don't use sg as iterator in sbc_verify_read target: Add DIF sense codes in transport_generic_request_failure target/sbc: Fix sbc_dif_copy_prot addr offset bug tcm_qla2xxx: Fix NAA formatted name for NPIV WWPNs tcm_qla2xxx: Perform configfs depend/undepend for base_tpg tcm_qla2xxx: Add NPIV specific enable/disable attribute logic qla2xxx: Check + fail when npiv_vports_inuse exists in shutdown qla2xxx: Fix qlt_lport_register base_vha callback race
