Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target updates from Nicholas Bellinger: "It's been usually busy for summer, with most of the efforts centered around TCMU developments and various target-core + fabric driver bug fixing activities. Not particularly large in terms of LoC, but lots of smaller patches from many different folks. The highlights include: - ibmvscsis logical partition manager support (Michael Cyr + Bryant Ly) - Convert target/iblock WRITE_SAME to blkdev_issue_zeroout (hch + nab) - Add support for TMR percpu LUN reference counting (nab) - Fix a potential deadlock between EXTENDED_COPY and iscsi shutdown (Bart) - Fix COMPARE_AND_WRITE caw_sem leak during se_cmd quiesce (Jiang Yi) - Fix TMCU module removal (Xiubo Li) - Fix iser-target OOPs during login failure (Andrea Righi + Sagi) - Breakup target-core free_device backend driver callback (mnc) - Perform TCMU add/delete/reconfig synchronously (mnc) - Fix TCMU multiple UIO open/close sequences (mnc) - Fix TCMU CHECK_CONDITION sense handling (mnc) - Fix target-core SAM_STAT_BUSY + TASK_SET_FULL handling (mnc + nab) - Introduce TYPE_ZBC support in PSCSI (Damien Le Moal) - Fix possible TCMU memory leak + OOPs when recalculating cmd base size (Xiubo Li + Bryant Ly + Damien Le Moal + mnc) - Add login_keys_workaround attribute for non RFC initiators (Robert LeBlanc + Arun Easi + nab)" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (68 commits) iscsi-target: Add login_keys_workaround attribute for non RFC initiators Revert "qla2xxx: Fix incorrect tcm_qla2xxx_free_cmd use during TMR ABORT" tcmu: clean up the code and with one small fix tcmu: Fix possbile memory leak / OOPs when recalculating cmd base size target: export lio pgr/alua support as device attr target: Fix return sense reason in target_scsi3_emulate_pr_out target: Fix cmd size for PR-OUT in passthrough_parse_cdb tcmu: Fix dev_config_store target: pscsi: Introduce TYPE_ZBC support target: Use macro for WRITE_VERIFY_32 operation codes target: fix SAM_STAT_BUSY/TASK_SET_FULL handling target: remove transport_complete pscsi: finish cmd processing from pscsi_req_done tcmu: fix sense handling during completion target: add helper to copy sense to se_cmd buffer target: do not require a transport_complete for SCF_TRANSPORT_TASK_SENSE target: make device_mutex and device_list static tcmu: Fix flushing cmd entry dcache page tcmu: fix multiple uio open/close sequences tcmu: drop configured check in destroy ...
