Subject: [PATCH 1/2] net: Fix the condition passed to sk_wait_event()
Date: Sat, 2 Oct 2010 16:49:16 -0700 (PDT) [thread overview]
Message-ID: <339313.23381.qm@web53706.mail.re2.yahoo.com> (raw)
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.
