context_tracking: Rename context_tracking_is_cpu_enabled() to context_tracking_enabled_this_cpu() (84e0dacd) · Commits · 戴 / test

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. Signed-off-by:
