Subject: [PATCH] [45/99] fat: Fix corrupt inode flags when remove ATTR_SYS flag

2.6.35-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: OGAWA Hirofumi <hirofumi@...l.parknet.co.jp>

commit 1adffbae22332bb558c2a29de19d9aca391869f6 upstream.

We are clearly missing '~' in fat_ioctl_set_attributes().
