perf record: Fix eternal wait for stillborn child
When execvp fails to find the specified command on the path we won't get SIGCHLD, so send a SIGUSR1 and exit right away. Current situation would require a SIGINT performed by the user and would produce meaningless summary. Now: [acme@emilia linux]$ ./foo -bash: ./foo: No such file or directory [acme@emilia linux]$ perf record ./foo ./foo: No such file or directory [acme@emilia linux]$ Acked-by: Thomas Gleixner <tglx@linutronix.de> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Mike Galbraith <efault@gmx.de> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Cc: Tom Zanussi <tzanussi@gmail.com> Cc: Thomas Gleixner <tglx@linutronix.de> LKML-Reference: <new-submission> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
