Halil Pasic 62a8690649 s390/virtio: handle find on invalid queue gracefully ... commit 3438b2c039b4bf26881786a1f3450f016d66ad11 upstream. A queue with a capacity of zero is clearly not a valid virtio queue. Some emulators report zero queue size if queried with an invalid queue index. Instead of crashing in this case let us just return -ENOENT. To make that work properly, let us fix the notifier cleanup logic as well.
