hm, that was supposed to shut itself off after 100 messages:
if (unlikely(clone_flags & (CLONE_DETACHED|CLONE_STOPPED))) {
static int __read_mostly count = 100;
if (count && printk_ratelimit()) {
char comm[TASK_COMM_LEN];
count--;
printk(KERN_INFO "fork(): process `%s' used deprecated "
"clone flags 0x%lx\n",
get_task_comm(comm, current),
clone_flags & (CLONE_DETACHED|CLONE_STOPPED));
}
}
I don't see how you got 151 instances. I guess I'm having another stupid
day.
It looks like a simple race, two threads do count-- before doing
if(count), resulting in an almost infinite loop. Probably.
atomic_test_and_dec might work.
