Subject: [PATCH v2 6/8] Coccinelle: atomic_as_refcounter: Use nested disjunctions in the first SmPL rule
Date: Mon, 16 Jul 2018 19:34:35 +0200	[thread overview]
Message-ID: <15372138-088d-81ce-3d3e-0b95f5d91ce9@users.sourceforge.net> (raw)
In-Reply-To: <5ca6ab58-e929-8468-74e2-012f987a0773@users.sourceforge.net>

From: Markus Elfring <elfring@users.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.
