Such errors are generally not related to ext2 structure problems, but
may be due to disk read errors that have not been recovered.
When ext2-fs search in a directory, it tries to read ahead asynchronously
severall directory blocks.
If an unrecovered IO error occurs on such a block, ext2 dir code then
sees a hole, but it is just an IO hole. :)
