From e0e4d82f3be60cfe8b10304c6daf3ca5973ae9e3 Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 7 Apr 2016 17:23:58 +0100 Subject: rxrpc: Create a null security type and get rid of conditional calls Create a null security type for security index 0 and get rid of all conditional calls to the security operations. We expect normally to be using security, so this should be of little negative impact. Signed-off-by: David Howells Signed-off-by: David S.
