From 3304b56401c4509ffaa74705b49edc9e13cee195 Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Fri, 29 Aug 2014 00:26:50 -0700 Subject: [PATCH] f2fs: fix wrong casting for dentry name The dentry name type is unsigned char *. If we don't match this type, some character codes can be changed by signed bit.
