Subject[PATCH v12 05/17] counter: Rename counter_count_function to counter_function
Date
The phrase "Counter Count function" is verbose and unintentionally
implies that function is a Count extension. This patch adjusts the
Counter subsystem code to use the more direct "Counter function" phrase
to make the intent of this code clearer.
