We sync our inode flags with ext2 and define them by hex values. But actually in commit 3669567(4 years ago), all these values are moved to include/linux/fs.h. So we'd better also use them as what ext2 did. So sync our inode flags with ext2 by using FS_*. Signed-off-by: Tao Ma <tao.ma@oracle.com> Signed-off-by: Joel Becker <joel.becker@oracle.com>
