Subject: [PATCH net-next 1/3] tipc: eliminate duplicated discard_rx_queue routine
From: Ying Xue <ying.xue@...driver.com>
The tipc function discard_rx_queue() is just a duplicated
implementation of __skb_queue_purge(). Remove the former
and directly invoke __skb_queue_purge().
In doing so, the underscores convey to the code reader, more
information about the current locking state that is assumed.
