This ends up\ncalling __nvme_fc_abort_outstanding_ios() which aborts requests in both\nadmin and io tagsets. In case fc_ctrl->tag_set was not initialized we\nsee the warning below. This is because ctrl.queue_count is initialized\nearly in nvme_fc_alloc_ctrl().\n\nnvme nvme0: NVME-FC{0}: starting error recovery Connectivity Loss\nINFO: trying to register non-static key.\nThe code is fine but needs lockdep annotation, or maybe\nlpfc 0000:ab:00.0: queue 0 connect admin queue failed (-6).\nyou didn't initialize this object before use?\nturning off the locking correctness validator.\nWorkqueue: nvme-reset-wq nvme_fc_ctrl_ioerr_work [nvme_fc]\nCall Trace:\n <TASK>\n dump_stack_lvl+0x57/0x80\n register_lock_class+0x567/0x580\n __lock_acquire+0x330/0xb90\n lock_acquire.part.0+0xad/0x210\n blk_mq_tagset_busy_iter+0xf9/0xc00\n __nvme_fc_abort_outstanding_ios+0x23f/0x320 [nvme_fc]\n nvme_fc_ctrl_ioerr_work+0x172/0x210 [nvme_fc]\n process_one_work+0x82c/0x1450\n worker_thread+0x5ee/0xfd0\n kthread+0x3a0/0x750\n ret_from_fork+0x439/0x670\n ret_from_fork_asm+0x1a/0x30\n </TASK>\n\nUpdate the check in __nvme_fc_abort_outstanding_ios() confirm that io\ntagset was created before iterating over busy requests.
