[PATCH 26/28] AF_RXRPC: Save the operation ID for debugging [try #2]

From: David Howells <dhowells_at_redhat.com>
Date: Wed, 05 Dec 2007 19:40:31 +0000


Save the operation ID to be used with a call that we're making for display through /proc/net/rxrpc_calls. This helps debugging stuck operations as we then know what they are.
