Subject: [PATCH 09/15] mke2fs: check return value of e2p_os2string()
Date: Mon, 29 Nov 2010 17:55:11 +0900 [thread overview]
Message-ID: <1291020917-8671-10-git-send-email-namhyung@gmail.com> (raw)
In-Reply-To: <1291020917-8671-1-git-send-email-namhyung@gmail.com>
e2p_os2string() calls malloc() so that it can return NULL.
Check it.
