A reproducer with a widened race window reports:\n\n  BUG: KASAN: slab-use-after-free in proc_remove+0x78/0x80\n  Read of size 8 at addr ffff8881478fea70 by task kpktgend_0/67\n  Call Trace:\n   proc_remove+0x78/0x80\n   pktgen_remove_device.isra.0+0x11c/0x4c0\n   pktgen_thread_worker+0x1214/0x6bc0\n   kthread+0x2c6/0x3b0\n  Allocated by task 95:\n   __proc_create+0x204/0x790\n   proc_create_data+0x72/0xe0\n   pktgen_thread_write+0xd61/0x1510\n  Freed by task 28:\n   kmem_cache_free+0xcb/0x3d0\n   proc_free_inode+0x5b/0x80\n   rcu_core+0x50a/0x1850\n  The buggy address belongs to the object at ffff8881478fea00\n   which belongs to the cache proc_dir_entry of size 192\n\nMove proc_remove() into the if_lock-protected list removal helper. Keep it\nbefore list_del_rcu() to preserve the ordering required by add_device().\nThe rename path must then finish replacing the entry before removal, or\nit observes that the device is no longer on the list.",
