you're right. How about the nice and simple version?
int __kill_pg_info(int sig, struct siginfo *info, pid_t pgrp) { struct task_struct *p; struct list_head *l; struct pid *pid; int retval; int found;
if (pgrp <= 0) return -EINVAL;
found = 0; retval = 0; for_each_task_pid(pgrp, PIDTYPE_PGID, p, l, pid) { int err;
found = 1; err = group_send_sig_info(sig, info, p); if (!retval) retval = err; } return found ? retval : -ESRCH; }
