  "message": "virtio: Fix used_idx wrap-around\n\nThe more_used() function compares the vq-\u003evring.used-\u003eidx with last_used_idx.\nSince vq-\u003evring.used-\u003eidx is a 16-bit integer, and last_used_idx is an\nunsigned int, this results in unpredictable behavior when vq-\u003evring.used-\u003eidx\nwraps around.\n\nThis patch corrects this by changing last_used_idx to the correct type.\n\nSigned-off-by: Anthony Liguori \u003caliguori@us.ibm.com\u003e\nSigned-off-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\n",
