Subject[PATCH 2/6] Coccinelle: atomic_as_refcounter: Optimise a disjunction in the first SmPL rule
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 2 Jul 2018 17:14:01 +0200

The names “fname2” till “fname6” do not care for different function
parameters in the disjunction at the end of a rule in a script
for the semantic patch language.
Thus reduce this disjunction by using a regular expression with
an alternation for an optimised constraint.
