Please go ahead and pull from: git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git for-next It's been a busy development cycle for target-core in a number of different areas. The fabric API usage for se_node_acl allocation is now within target-core code, dropping the external API callers for all fabric drivers tree-wide. There is a new conversion to RCU hlists for se_node_acl and se_portal_group LUN mappings, that turns fast-past LUN lookup into a completely lock-less code-path. It also removes the original hard-coded limitation of 256 LUNs per fabric endpoint. The configfs attributes for backends can now be shared between core and driver code, allowing existing drivers to use common code while still allowing flexibility for new backend provided attributes. The highlights include: - Merge sbc_verify_dif_* into common code (sagi) - Remove iscsi-target support for obsolete IFMarker/OFMarker (Christophe Vu-Brugier) - Add bidi support in target/user backend (ilias + vangelis + agover) - Move se_node_acl allocation into target-core code (hch) - Add crc_t10dif_update common helper (akinobu + mkp) - Handle target-core odd SGL mapping for data transfer memory (akinobu) - Move transport ID handling into target-core (hch) - Move task tag into struct se_cmd + support 64-bit tags (bart) - Convert se_node_acl->device_list[] to RCU hlist (nab + hch + paulmck) - Convert se_portal_group->tpg_lun_list[] to RCU hlist (nab + hch + paulmck) - Simplify target backend driver registration (hch) - Consolidate + simplify target backend attribute implementations (hch + nab) - Subsume se_port + t10_alua_tg_pt_gp_member into se_lun (hch) - Drop lun_sep_lock for se_lun->lun_se_dev RCU usage (hch + nab) - Drop unnecessary core_tpg_register TFO parameter (nab) - Use 64-bit LUNs tree-wide (hannes) - Drop left-over TARGET_MAX_LUNS_PER_TRANSPORT limit (hannes) Thank you, --nab Akinobu Mita (4): target: Fix inconsistent address passed to kunmap_atomic() in sbc_dif_copy_prot() target: ensure se_cmd->t_prot_sg is allocated when required lib: introduce crc_t10dif_update() target: handle odd SG mapping for data transfer memory Bart Van Assche (5): target: Remove first argument of target_{get,put}_sess_cmd() target: Move task tag into struct se_cmd + support 64-bit tags ib_srpt: Remove set-but-not-used variables target: Remove set-but-not-used-variables target: Simplify LUN shutdown code Christoph Hellwig (31): target: fix DPO and FUA bit checks tcm_loop: remove struct tcm_loop_nacl tcm_usb: remove struct usbg_nacl sbp_target: remove struct sbp_nacl vhost/scsi: remove struct vhost_scsi_nacl target: make the tpg_get_default_depth method optional target: refactor init/drop_nodeacl methods target: refactor node ACL allocation target: move node ACL allocation to core code target/iscsi: stop using se_tpg_fabric_ptr tcm_loop: stop using se_tpg_fabric_ptr tcm_fc: stop using se_tpg_fabric_ptr target: change core_tpg_register prototype target: remove the get_fabric_proto_ident method target: move transport ID handling to the core target: don't copy fabric ops target: put struct target_fabric_configfs on a diet target: remove struct target_fabric_configfs_template target: target_core_configfs.h is not needed in fabric drivers target: remove ->put_session method target/pr: cleanup core_scsi3_pr_seq_non_holder target: simplify backend driver registration target: consolidate backend attribute implementations target: simplify backend attribute implementation target: Subsume se_port + t10_alua_tg_pt_gp_member into se_lun target: replace se_cmd->execute_rw with a protocol_data field target: simplify UNMAP handling target: implement WRITE_SAME with UNMAP bit using ->execute_unmap target: consolidate version defines target: remove unused TARGET_CORE_CONFIG_ROOT define target: remove target_core_configfs.h Christophe Vu-Brugier (3): iscsi-target: remove support for obsolete markers target: fix a log message in se_dev_set_emulate_rest_reord() iscsi-target: fix variable name typo in iscsi_check_acceptor_state() Hannes Reinecke (8): target: use 64-bit LUNs target: Remove TARGET_MAX_LUNS_PER_TRANSPORT target_core_alua: Correct UA handling when switching states target: Remove 'ua_nacl' pointer from se_ua structure target: use 'se_dev_entry' when allocating UAs target: Send UA on ALUA target port group change target: Send UA upon LUN RESET tmr completion target: Send UA when changing LUN inventory Ilias Tsitsimpis (5): driver/user: Don't warn for DMA_NONE data direction target/loop: Enable VARLEN CDB support target/transport: Always initialize bidi fields in se_cmd target/user: Refactor data area allocation code target/user: Add support for bidirectional commands Nicholas Bellinger (16): target: Convert se_node_acl->device_list[] to RCU hlist target/pr: Use atomic bitop for se_dev_entry->deve_flags reservation check target/pr: Change alloc_registration to avoid pr_reg_tg_pt_lun target: Convert se_portal_group->tpg_lun_list[] to RCU hlist target: Convert se_tpg->acl_node_lock to ->acl_node_mutex target: Convert core_tpg_deregister to use list splice target: Drop unused se_lun->lun_acl_list target: Only reset specific dynamic entries during lun_group creation target: Drop left-over se_lun->lun_status target: Drop lun_sep_lock for se_lun->lun_se_dev RCU usage target: Drop se_lun->lun_active for existing percpu lun_ref target: Drop unnecessary core_tpg_register TFO parameter target: Drop duplicate + unused se_dev_check_wce xen-scsiback: Fix compile warning for 64-bit LUN target: Convert se_lun->lun_deve_lock to normal spinlock target: Bump core version to v5.0 Sagi Grimberg (4): target: Merge sbc_verify_dif_read|write target/file: Remove fd_prot bounce buffer target/sbc: Fix sbc_dif_verify inconsistent map/unmap target/user: Fix inconsistent kmap_atomic/kunmap_atomic Documentation/target/tcm_mod_builder.py | 277 +---- Documentation/target/tcm_mod_builder.txt | 4 +- Documentation/target/tcmu-design.txt | 2 +- drivers/infiniband/ulp/isert/ib_isert.c | 6 +- drivers/infiniband/ulp/srpt/ib_srpt.c | 183 +--- drivers/infiniband/ulp/srpt/ib_srpt.h | 23 +- drivers/scsi/qla2xxx/qla_target.c | 52 +- drivers/scsi/qla2xxx/qla_target.h | 1 -
