Because the NBD I/O submission path (`nbd_queue_rq()` -> `nbd_handle_cmd()`) acquires `&nsock->tx_lock` during direct memory reclaim (`fs_reclaim`), and core slab cache management establishes `cpu_hotplug_lock -> slab_mutex -> fs_reclaim` (via `kmem_cache_destroy()` and `__kmem_cache_create_args()`), this introduces an ABBA circular locking dependency that can deadlock the kernel under memory pressure. full analysis: https://syzkaller.appspot.com/x/ai_root_cause?x=72fceb8393e04ce876d9 IMPORTANT: if you fix the issue, please add the following tag to the commit: Reported-by:
