While at it, let re-arrange the struct to remove holes.
Before, pahole reports
/* size: 232, cachelines: 4, members: 17 */
/* sum members: 224, holes: 2, sum holes: 8 */
/* last cacheline: 40 bytes */
After the change, the report changes to
/* size: 224, cachelines: 4, members: 17 */
/* last cacheline: 32 bytes */
