>From 48c9c4f61a7d7ea98538e02631a981a429281005 Mon Sep 17 00:00:00 2001 From: Markus Elfring <elfr...@users.sourceforge.net> Date: Wed, 5 Mar 2014 18:15:34 +0100 Subject: [PATCH 1/5] Addition of a semantic patch file for showing unnecessary checks before a few known functions This semantic patch pattern tries to find source code places where a check is performed for an expression that is passed to a function (like "kfree") which checks this single parameter itself for usability. Redundant value or pointer checks can be avoided here. The pattern contains a special comment in a regular expression for a SmPL constraint which supports extensions.
