Subject: [PATCH 4/7] context_tracking: Add stub context_tracking_is_enabled
Date: Tue, 10 Mar 2015 15:37:15 +0100	[thread overview]
Message-ID: <1425998238-4954-5-git-send-email-fweisbec@gmail.com> (raw)
In-Reply-To: <1425998238-4954-1-git-send-email-fweisbec@gmail.com>

From: Rik van Riel <riel@redhat.com>

With code elsewhere doing something conditional on whether or not
context tracking is enabled, we want a stub function that tells us
context tracking is not enabled, when CONFIG_CONTEXT_TRACKING is
not set.
