Subject: [PATCH v2 6/8] Coccinelle: atomic_as_refcounter: Use nested
 disjunctions in the first SmPL rule

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 16 Jul 2018 18:22:53 +0200

Six function names were specified for a search of function calls
by the means of a disjunction in the rule of a script for
the semantic patch language.
Refactor them into two groups so that the SmPL code repetition
could be reduced a bit.
