Subject: [PATCH v3 02/11] contrib/coccinelle: add basic Coccinelle transforms
Date: Fri, 24 Jun 2016 23:09:20 +0000	[thread overview]
Message-ID: <20160624230929.82222-3-sandals@crustytoothpaste.net> (raw)
In-Reply-To: <20160624230929.82222-1-sandals@crustytoothpaste.net>

Coccinelle (http://coccinelle.lip6.fr/) is a program which performs
mechanical transformations on C programs using semantic patches.  These
semantic patches can be used to implement automatic refactoring and
maintenance tasks.

Add a set of basic semantic patches to convert common patterns related
to the struct object_id transformation, as well as a README.
