Subject: [PATCH 12/25] context_tracking: Rename context_tracking_is_cpu_enabled() to context_tracking_enabled_this_cpu()
Date: Wed, 14 Nov 2018 03:45:56 +0100	[thread overview]
Message-ID: <1542163569-20047-13-git-send-email-frederic@kernel.org> (raw)
In-Reply-To: <1542163569-20047-1-git-send-email-frederic@kernel.org>

Standardize the naming on top of the context_tracking_enabled_*() base.
Also make it clear we are checking the context tracking state of the
*current* CPU with this function. We'll need to add an API to check that
state on remote CPUs as well, so we must disambiguate the naming.
