Subject: [PATCH 2/3] Btrfs-progs: add kstrdup() return value check
Date: Sun, 30 Jun 2013 12:51:45 +0100 [thread overview]
Message-ID: <1372593106-6593-3-git-send-email-fdmanana@gmail.com> (raw)
In-Reply-To: <1372593106-6593-1-git-send-email-fdmanana@gmail.com>
When allocating a btrfs_device structure, device_list_add()
in volumes.c was not checking if the call to duplicate the
label string succeeded or not.
