[PATCH 1/2] net: Fix the condition passed to sk_wait_event()

From: Nagendra Tomar
Date: Sat Oct 02 2010 - 19:49:27 EST


This patch fixes the sk_wait_event() condition in the sk_stream_wait_connect()
function. With this change, we correctly check for the TCPF_ESTABLISHED and
TCPF_CLOSE_WAIT states and avoid potentially returning success when there
might be an error on the socket.
