[2/2] [TCP] Fix sk_forward_alloc underflow in tcp_sendmsg

2005-09-01 Thread Herbert Xu
Hi: I've finally found a potential cause of the sk_forward_alloc underflows that people have been reporting sporadically. When tcp_sendmsg tacks on extra bits to an existing TCP_PAGE we don't check sk_forward_alloc even though a large amount of time may have elapsed since we allocated the page.
