I have most recently torn apart the VOP_READDIR interface to get rid of "cookies" for NFS; this is a pretty significant change, since it classes seperate FS "consumers" (the syscall interface is a consumer, NFS is a consumer, any other kernel file server -- NetWare, AFS, RFS, etc. -- would also be a consumer). > Does JFS also use linear directory structures though?
