From 2db00321815e20f4a7ff9df43f7cf2073085683d Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Tue, 3 Aug 2010 21:35:36 +0000 Subject: [PATCH] IB/ehca: Drop unnecessary NULL test list_for_each_entry binds its first argument to a non-null value, and thus any null test on the value of that argument is superfluous. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @@ iterator I; expression x; statement S,S1,S2; @@ I(x,...) { <... - if (x == NULL && ...)
