Merge git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target fixes from Nicholas Bellinger: "This includes the long awaited series to address a set of bugs around active I/O remote-port LUN_RESET, as well as properly handling this same case with concurrent fabric driver session disconnect -> reconnect. Note this set of LUN_RESET bug-fixes has been surviving extended testing on both v4.5-rc1 and v3.14.y code over the last weeks, and is CC'ed for stable as it's something folks using multiple ESX connected hosts with slow backends can certainly trigger. The highlights also include: - Fix WRITE_SAME/DISCARD emulation 4k sector conversion in target/iblock (Mike Christie) - Fix TMR abort interaction and AIO type TMR response in qla2xxx target (Quinn Tran + Swapnil Nagle) - Fix >= v3.17 stale descriptor pointer regression in qla2xxx target (Quinn Tran) - Fix >= v4.5-rc1 return regression with unmap_zeros_data_store new configfs store handler (nab) - Add CPU affinity flag + convert qla2xxx to use bit (Quinn + HCH + Bart)" * git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: qla2xxx: use TARGET_SCF_USE_CPUID flag to indiate CPU Affinity target/transport: add flag to indicate CPU Affinity is observed target: Fix incorrect unmap_zeroes_data_store return qla2xxx: Use ATIO type to send correct tmr response qla2xxx: Fix stale pointer access. target/user: Fix cast from pointer to phys_addr_t target: Drop legacy se_cmd->task_stop_comp + REQUEST_STOP usage target: Fix race with SCF_SEND_DELAYED_TAS handling target: Fix remote-port TMR ABORT + se_cmd fabric stop target: Fix TAS handling for multi-session se_node_acls target: Fix LUN_RESET active TMR descriptor handling target: Fix LUN_RESET active I/O handling for ACK_KREF qla2xxx: Fix TMR ABORT interaction issue between qla2xxx and TCM qla2xxx: Fix warning reported by static checker target: Fix WRITE_SAME/DISCARD conversion to linux 512b sectors
