fwiw, I applied the exact same printk to the T5, namely,
printk(KERN_INFO "sizeof sock %ld \n"
"sizeof request_sock %ld\n"
"sizeof inet_request_sock %ld\n"
"offsetof sk_policy 1 %ld\n",
sizeof (struct sock), sizeof (struct request_sock),
sizeof (struct inet_request_sock),
offsetof(struct sock, sk_policy[1]));
and got this:
sizeof sock 1216
sizeof request_sock 312
sizeof inet_request_sock 328
offsetof sk_policy 1 520
So it's good to know that crash does not lie.
But then it's odd that the struct sizes (esp of things like
request_sock, which are not config dependant) are not the same.
