Currently metadata writing errors are ignored and not returned from
sys_fsync on ext2 and ext3 filesystems.  That is, at least ext2 and ext3.

Both ext2 and ext3 resort to sync_inode() in their ->sync_inode method,
which in turn calls ->write_inode.  ->write_inode method has void type, and
any IO errors happening inside are lost.

Make ->write_inode return the error code?
