[PATCH 3/4] Update the UNIX buffer restore code to match the new format saved in the image file

[Serge E. Hallyn]

Quoting Dan Smith (danms at us.ibm.com):
>  	/* Make sure there's room in the send buffer */
>  	sndbuf = sk->sk_sndbuf;
> -	if (((sk->sk_sndbuf - atomic_read(&sk->sk_wmem_alloc)) < len) &&
> +	if (((sk->sk_sndbuf - atomic_read(&sk->sk_wmem_alloc)) < h->lin_len) &&
>  	    capable(CAP_NET_ADMIN))
> -		sk->sk_sndbuf += len;
> +		sk->sk_sndbuf += h->lin_len;
>  	else
>  		sk->sk_sndbuf = sysctl_wmem_max;

Can you explain what's going on here?  'if the size of the send buffer
minus tranmit queue bytes committed is less than linear length,
then if you're privileged you add h->len to sk->sk_sndbuf, but if
either you're not privileged or the length was greater than linear
length, then you add sysctl_wmem_max.'  ?

I realize that's a question on the original code, not on this
patch...
