Motivation: In order NFS server to support extended attributes, they should be exposed by under laying vfs interface. Modification: introduce VirtualFileSystem#get/set/list/removeXattr methods with default implementations. Update PseudoFs to check permissions and bypass requests to backing implementation. To read or list extended attributes, read permission on the file is required To set or remove extended attributes, write permissions on the file is required Result: ground work for extended attribute support.
