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: - Introduce configfs support for unlocked configfs_depend_item() (krzysztof + andrezej) - Conversion of usb-gadget target driver to new function registration interface (andrzej + sebastian) - Enable qla2xxx FC target mode support for Extended Logins (himansu + giridhar) - Enable qla2xxx FC target mode support for Exchange Offload (himansu + giridhar) - Add qla2xxx FC target mode irq affinity notification + selective command queuing. (quinn + himanshu) - Fix iscsi-target deadlock in se_node_acl configfs deletion (sagi + nab) - Convert se_node_acl configfs deletion + se_node_acl->queue_depth to proper se_session->sess_kref + target_get_session() usage. (hch + sagi + nab) - Fix long-standing race between se_node_acl->acl_kref get and get_initiator_node_acl() lookup. (hch + nab) - Fix target/user block-size handling, and make sure netlink reaches all network namespaces (sheng + andy) Note there is an outstanding bug-fix series for remote I_T nexus port TMR LUN_RESET has been posted and still being tested, and will likely become post -rc1 material at this point" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (56 commits) scsi: qla2xxxx: avoid type mismatch in comparison target/user: Make sure netlink would reach all network namespaces target: Obtain se_node_acl->acl_kref during get_initiator_node_acl target: Convert ACL change queue_depth se_session reference usage iscsi-target: Fix potential dead-lock during node acl delete ib_srpt: Convert acl lookup to modern get_initiator_node_acl usage tcm_fc: Convert acl lookup to modern get_initiator_node_acl usage tcm_fc: Wait for command completion before freeing a session target: Fix a memory leak in target_dev_lba_map_store() target: Support aborting tasks with a 64-bit tag usb/gadget: Remove set-but-not-used variables target: Remove an unused variable target: Fix indentation in target_core_configfs.c target/user: Allow user to set block size before enabling device iser-target: Fix non negative ERR_PTR isert_device_get usage target/fcoe: Add tag support to tcm_fc qla2xxx: Check for online flag instead of active reset when transmitting responses qla2xxx: Set all queues to 4k qla2xxx: Disable ZIO at start time. qla2xxx: Move atioq to a different lock to reduce lock contention ...
