* HISTORY
* 27-Sep-89 Morris Meyer (mmeyer) at NeXT
* NFS 4.0 Changes: ucred definition moved to ucred.h.
* Addition of u_auid.
*
* 28-Apr-88 David Golub (dbg) at Carnegie-Mellon University
* Move u_rpause and u_rfs from thread to task U-area - they are
* both global process state.
*
* 26-Feb-88 David Kirschen (kirschen) at Encore Computer Corporation
* Add include of param.h for NGROUPS, etc.
*
* 19-Nov-87 Avadis Tevanian (avie) at Carnegie-Mellon University
* Eliminated conditionals, purged history.
