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)"
