[PATCH v2 3/8] Coccinelle: atomic_as_refcounter: Optimise a disjunction in the first SmPL rule

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Mon, 16 Jul 2018 17:43:49 +0200

The variables âfname2â till âfname6â 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.
