From 113f04a836481e9ecc26e8dee8b0e4d52878a288 Mon Sep 17 00:00:00 2001 From: Daniel Walker Date: Mon, 21 Sep 2009 17:04:35 -0700 Subject: [PATCH] checkpatch: handle C99 comments correctly (performance issue) This fixes the sanitation process in checkpatch.pl so that it blocks out the text after a C99 style comment the same way it does with block style comments. This prevents the text from getting processed as regular code.
