Date: Fri, 2 Mar 2012 20:16:45 -0500 From: Namjae Jeon <linkinjeon@...il.com> To: hirofumi@...l.parknet.co.jp Cc: linux-kernel@...r.kernel.org, Namjae Jeon <linkinjeon@...il.com>, Ravishankar N <cyberax82@...il.com> Subject: [PATCH 2/2] fat: Fix bug in enforcing Long File Name length. Since '*outlen' is initialized to zero,it is currently possible to create a f ilename of length (FAT_LFN_LEN +1) when utf8 is not enabled.To enforce the FA T_LFN_LEN limit, we must perform one less iteration.
