Ladi Prosek 57094547df virtio-input: fix eventq batching ... virtio_input_send buffers input events until it sees a SYNC. Then it either sends or drops the entire batch, depending on whether eventq has enough space available. The case to avoid here is partial sends where only part of the batch would get to the guest. Using virtqueue_get_avail_bytes to check the state of eventq was not correct. The queue may have a smaller number of larger buffers available so bytes may be enough but the batch would still not be possible to send, leading to the "Huh? No vq elem available" error. Instead of checking available bytes, this patch optimistically pops buffers from the queue and puts them back in case it runs out of space and the batch needs to be dropped.
