Are we talking about the on disk directory structure here? If so, the reason for this crap is that the default representation is intended to match the default FS on disk representation, such that minimal effor can be expended in the copy/convert process. Doug Rabson and I discussed this at length more than a year ago, with regard to the implied conversion requirements of VOP_READDIR, and what really needs to be done is pass back an FS block reference and seperate the conversion from the allocation. This would have the nice side effect of removing the need for the cookie code, since you seperate into "get atomic block"/"convert element from atomic block". Currently, the purpose of the cookie code is to deal with a "user buffer" supplied by NFS being too small for the number of real entries requested but not too small for the number of NFS representations of those entries requested (ie: transport block smaller than FS block).
