If perf bench messaging in process mode exits abnormally, the forked child processes does not exit.
The test result is as follows:
# perf bench sched messaging -l 1000000 -g 1 & [4] 553 # Running 'sched/messaging' benchmark: # kill -15 533 # ps -ef | grep perf root 425 371 0 09:11 pts/0 00:00:00 perf bench sched messaging -l 1000000 -g 1 root 426 425 17 09:11 pts/0 00:01:56 perf bench sched messaging -l 1000000 -g 1 root 427 425 17 09:11 pts/0 00:01:55 perf bench sched messaging -l 1000000 -g 1 root 428 425 17 09:11 pts/0 00:01:55 perf bench sched messaging -l 1000000 -g 1 root 429 425 17 09:11 pts/0 00:01:55 perf bench sched messaging -l 1000000 -g 1 root 430 425 17 09:11 pts/0 00:01:55 perf bench sched messaging -l 1000000 -g 1 root 431 425 17 09:11 pts/0 00:01:56 perf bench sched messaging -l 1000000 -g 1 root 432 425 17 09:11 pts/0 00:01:55 perf bench sched messaging -l 1000000 -g 1 root 433 425 17 09:11 pts/0 00:01:55 perf bench sched messaging -l 1000000 -g 1 root 434 425 17 09:11 pts/0 00:01:55 perf bench sched messaging -l 1000000 -g 1 root 435 425 17 09:11 pts/0 00:01:55 perf bench sched messaging -l 1000000 -g 1 root 436 425 17 09:11 pts/0 00:01:55 perf bench sched messaging -l 1000000 -g 1 root 437 425 17 09:11 pts/0 00:01:55 perf bench sched messaging -l 1000000 -g 1 root 438 425 17 09:11 pts/0 00:01:55 perf bench sched messaging -l 1000000 -g 1 root 439 425 17 09:11 pts/0 00:01:55 perf bench sched messaging -l 1000000 -g 1 root 440 425 17 09:11 pts/0 00:01:55 perf bench sched messaging -l 1000000 -g 1 root 441 425 17 09:11 pts/0 00:01:55 perf bench sched messaging -l 1000000 -g 1 root 442 425 17 09:11 pts/0 00:01:55 perf bench sched messaging -l 1000000 -g 1 root 443 425 17 09:11 pts/0 00:01:55 perf bench sched messaging -l 1000000 -g 1 root 444 425 17 09:11 pts/0 00:01:54 perf bench sched messaging -l 1000000 -g 1 root 445 425 17 09:11 pts/0 00:01:55 perf bench sched messaging -l 1000000 -g 1 root 446 425 16 09:11 pts/0 00:01:50 perf bench sched messaging -l 1000000 -g 1 root 447 425 16 09:11 pts/0 00:01:49 perf bench sched messaging -l 1000000 -g 1 root 448 425 16 09:11 pts/0 00:01:50 perf bench sched messaging -l 1000000 -g 1 root 449 425 16 09:11 pts/0 00:01:49 perf bench sched messaging -l 1000000 -g 1 root 450 425 16 09:11 pts/0 00:01:50 perf bench sched messaging -l 1000000 -g 1 root 451 425 16 09:11 pts/0 00:01:50 perf bench sched messaging -l 1000000 -g 1 root 452 425 16 09:11 pts/0 00:01:50 perf bench sched messaging -l 1000000 -g 1 root 453 425 16 09:11 pts/0 00:01:49 perf bench sched messaging -l 1000000 -g 1 root 454 425 16 09:11 pts/0 00:01:49 perf bench sched messaging -l 1000000 -g 1 <SNIP>
