Last Breaking-Event-Address: [<00000000002141b6>] blk_remove_plug+0xae/0xb8 The FC pass-through support triggers the WARN_ON(!irqs_disabled()) in blk_plug_device. Since blk_plug_device requires being called with disabled interrupts, use spin_lock_irqsave in fc_bsg_goose_queue to disable the interrupts before calling into the block layer.
