Abstract
A method, computer program product and data processing system for accessing extended attributes. An extended attribute descriptor in a dinode may be read to determine if there exists extended attributes associated with a file system object that is associated with the dinode. An extended attribute descriptor points to a dinodex associated with the dinode if there exists an extended attribute associated with the file system object. The dinodex may then be read to retrieve the extended attritbutes stored either inside or outside the dinodex. However, if there is no extended attribute associated with that particular file system object, then the extended attribute descriptor comprises a null value and does not point to a dinodex associated with the dinode.
