Merge git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target fixes from Nicholas Bellinger: "There has been work in a number of different areas over the last weeks, including: - Fix target-core-user (TCMU) back-end bi-directional handling (Xiubo Li + Mike Christie + Ilias Tsitsimpis) - Fix iscsi-target TMR reference leak during session shutdown (Rob Millner + Chu Yuan Lin) - Fix target_core_fabric_configfs.c race between LUN shutdown + mapped LUN creation (James Shen) - Fix target-core unknown fabric callback queue-full errors (Potnuri Bharat Teja) - Fix iscsi-target + iser-target queue-full handling in order to support iw_cxgb4 RNICs. (Potnuri Bharat Teja + Sagi Grimberg) - Fix ALUA transition state race between multiple initiator (Mike Christie) - Drop work-around for legacy GlobalSAN initiator, to allow QLogic 57840S + 579xx offload HBAs to work out-of-the-box in MSFT environments. (Martin Svec + Arun Easi) Note that a number are CC'ed for stable, and although the queue-full bug-fixes required for iser-target to work with iw_cxgb4 aren't CC'ed here, they'll be posted to Greg-KH separately" * git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: tcmu: Skip Data-Out blocks before gathering Data-In buffer for BIDI case iscsi-target: Drop work-around for legacy GlobalSAN initiator target: Fix ALUA transition state race between multiple initiators iser-target: avoid posting a recv buffer twice iser-target: Fix queue-full response handling iscsi-target: Propigate queue_data_in + queue_status errors target: Fix unknown fabric callback queue-full errors tcmu: Fix wrongly calculating of the base_command_size tcmu: Fix possible overwrite of t_data_sg's last iov[] target: Avoid mappedlun symlink creation during lun shutdown iscsi-target: Fix TMR reference leak during session shutdown usb: gadget: Correct usb EP argument for BOT status request tcmu: Allow cmd_time_out to be set to zero (disabled)
