Subject[PATCH 5/6] Coccinelle: atomic_as_refcounter: Use nested disjunctions in two SmPL rules
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 2 Jul 2018 19:21:28 +0200

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