From 24a461d537f49f9da6533d83100999ea08c6c755 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Sat, 10 Jul 2010 12:06:44 +0200 Subject: [PATCH] trace: strlen() return doesn't account for the NULL We need to add one to the strlen() return because of the NULL character. The type->name here generally comes from the kernel and I don't think any of them come close to being MAX_TRACER_SIZE (100) characters long so this is basically a cleanup.
