I added a trace_printk() in inet_bind_bucket_destroy() to print out
some information on the socket used by xs_bind(), and it shows that the
bind destroy is called, but the list is not empty.
/*
* Caller must hold hashbucket lock for this tb with local BH disabled
*/
void inet_bind_bucket_destroy(struct kmem_cache *cachep, struct
inet_bind_bucket *tb)
{
if (!current->mm && xs_port == tb->port) {
trace_printk("destroy %d empty=%d %p\n",
tb->port, hlist_empty(&tb->owners), tb);
trace_dump_stack(1);
}
if (hlist_empty(&tb->owners)) {
__hlist_del(&tb->node);
kmem_cache_free(cachep, tb);
}
}
I created "xs_port" to hold the port of the variable used by xs_bind,
and when it is called, the hlist_empty(&tb->owners) returns false.
I'll add more trace_printks to find out where those owners are being
added.
