[PATCH 05/14] context_tracking: s/context_tracking_is_enabled/context_tracking_enabled()
From: Frederic Weisbecker
Date: Tue Oct 15 2019 - 22:57:26 EST
Remove the superfluous "is" in the middle of the name. We want to
standardize the naming so that it can be expanded through suffixes:
context_tracking_enabled()
context_tracking_enabled_cpu()
context_tracking_enabled_this_cpu()
