Thanks, applied both, the final layout for 'struct thread_runtime':
[root@jouet perf]# pahole -C thread_runtime ~/bin/perf
struct thread_runtime {
u64 last_time; /* 0 8 */
u64 dt_run; /* 8 8 */
u64 dt_sleep; /* 16 8 */
u64 dt_iowait; /* 24 8 */
u64 dt_preempt; /* 32 8 */
u64 dt_delay; /* 40 8 */
u64 ready_to_run; /* 48 8 */
struct stats run_stats; /* 56 40 */
/* --- cacheline 1 boundary (64 bytes) was 32 bytes ago --- */
u64 total_run_time; /* 96 8 */
u64 total_sleep_time; /* 104 8 */
u64 total_iowait_time; /* 112 8 */
u64 total_preempt_time; /* 120 8 */
/* --- cacheline 2 boundary (128 bytes) --- */
u64 total_delay_time; /* 128 8 */
int last_state; /* 136 4 */
char shortname[3]; /* 140 3 */
_Bool comm_changed; /* 143 1 */
u64 migrations; /* 144 8 */
/* size: 152, cachelines: 3, members: 17 */
/* last cacheline: 24 bytes */
};
