Subject: [PATCH 3/6] nohz: add stub context_tracking_is_enabled
Date: Tue, 10 Feb 2015 09:41:47 -0500 [thread overview]
Message-ID: <1423579310-24555-4-git-send-email-riel@redhat.com> (raw)
In-Reply-To: <1423579310-24555-1-git-send-email-riel@redhat.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.
