This is kernel driver problem too. It seems our knowledge about
attribute list a bit incorrect. ntfs_external_attr_find written in mind
with that attributes in the MFT record follow in same order as they
follow in attribute list. Metadata (link to which I send in previous
email) demonstrates vice-versa. FILE_NAME attributes follow in order 2,
3 (instance numbers) in the attribute list, but 3, 2 in the MFT record.
