From 8b7fac50ab7f2668c43795c135025c472922a344 Mon Sep 17 00:00:00 2001 From: David Howells Date: Wed, 7 Sep 2016 15:28:54 +0100 Subject: rxrpc: Pass the connection pointer to rxrpc_post_packet_to_call() Pass the connection pointer to rxrpc_post_packet_to_call() as the call might get disconnected whilst we're looking at it, but the connection pointer determined by rxrpc_data_read() is guaranteed by RCU for the duration of the call.
