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: - enable dual mode (initiator + target) qla2xxx operation. (Quinn + Himanshu) - add a framework for qla2xxx async fabric discovery. (Quinn + Himanshu) - enable iscsi PDU DDP completion offload in cxgbit/T6 NICs. (Varun) - fix target-core handling of aborted failed commands. (Bart) - fix a long standing target-core issue NULL pointer dereference with active I/O LUN shutdown. (Rob Millner + Bryant + nab)" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (44 commits) target: Add counters for ABORT_TASK success + failure iscsi-target: Fix early login failure statistics misses target: Fix NULL dereference during LUN lookup + active I/O shutdown target: Delete tmr from list before processing target: Fix handling of aborted failed commands uapi: fix linux/target_core_user.h userspace compilation errors target: export protocol identifier qla2xxx: Fix a warning reported by the "smatch" static checker target/iscsi: Fix unsolicited data seq_end_offset calculation target/cxgbit: add T6 iSCSI DDP completion feature target/cxgbit: Enable DDP for T6 only if data sequence and pdu are in order target/cxgbit: Use T6 specific macros to get ETH/IP hdr len target/cxgbit: use cxgb4_tp_smt_idx() to get smt idx target/iscsi: split iscsit_check_dataout_hdr() target: Remove command flag CMD_T_DEV_ACTIVE target: Remove command flag CMD_T_BUSY target: Move session check from target_put_sess_cmd() into target_release_cmd_kref() target: Inline transport_cmd_check_stop() target: Remove an overly chatty debug message target: Stop execution if CMD_T_STOP has been set ...
