Subject: [PATCH 001/001] net: Add tx_queue/rx_queue info to /proc/net/unix
Date: Sat, 28 Jan 2012 21:37:52 -0500	[thread overview]
Message-ID: <CAB0C5qK1FGc5xhGxGzpmELbWfC6GVVxEB9Zan_nU9cC_MxMzew@mail.gmail.com> (raw)

From: Ryan Hajdaj <rhajdaj@gmail.com>

Add tx_queue/rx_queue info to /proc/net/unix (unix_seq_show)

Signed-off-by: Ryan Hajdaj <rhajdaj@gmail.com>
Tested-by: Ryan Hajdaj <rhajdaj@gmail.com>
---
tx_queue/rx_queue info is useful in systems with multiple processes
using Unix Domain sockets to communicate, as it can be used to check
process health "at a glance".
Unit tested on Unix stream and datagram sockets.
