[PATCH 1/8] Add basic Coccinelle transforms.

From: brian m. carlson <sandals@crustytoothpaste.net>
Date: Jun 7, 2016, 00:57 UTC
Message-ID: <20160607005716.69222-2-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.
