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: - Update vhost-scsi to support F_ANY_LAYOUT using mm/iov_iter.c logic, and signal VERSION_1 support (MST + Viro + nab) - Fix iscsi/iser-target to remove problematic active_ts_set usage (Gavin Guo) - Update iscsi/iser-target to support multi-sequence sendtargets (Sagi) - Fix original PR_APTPL_BUF_LEN 8k size limitation (Martin Svec) - Add missing WRITE_SAME end-of-device sanity check (Bart) - Check for LBA + sectors wrap-around in sbc_parse_cdb() (nab) - Other various minor SPC/SBC compliance fixes based upon Ronnie Sahlberg test suite (nab)" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (32 commits) target: Set LBPWS10 bit in Logical Block Provisioning EVPD target: Fail UNMAP when emulate_tpu=0 target: Fail WRITE_SAME w/ UNMAP=1 when emulate_tpws=0 target: Add sanity checks for DPO/FUA bit usage target: Perform PROTECT sanity checks for WRITE_SAME target: Fail I/O with PROTECT bit when protection is unsupported target: Check for LBA + sectors wrap-around in sbc_parse_cdb target: Add missing WRITE_SAME end-of-device sanity check iscsi-target: Avoid IN_LOGOUT failure case for iser-target target: Fix PR_APTPL_BUF_LEN buffer size limitation iscsi-target: Drop problematic active_ts_list usage iscsi/iser-target: Support multi-sequence sendtargets text response iser-target: Remove duplicate function names vhost/scsi: potential memory corruption vhost/scsi: Global tcm_vhost -> vhost_scsi rename vhost/scsi: Drop left-over scsi_tcq.h include vhost/scsi: Set VIRTIO_F_ANY_LAYOUT + VIRTIO_F_VERSION_1 feature bits vhost/scsi: Add ANY_LAYOUT support in vhost_scsi_handle_vq vhost/scsi: Add ANY_LAYOUT iov -> sgl mapping prerequisites vhost/scsi: Change vhost_scsi_map_to_sgl to accept iov ptr + len ...
