no longer contains kernel specific data structures, but rather only scalar values and structures that are already part of the kernel/user interface, specifically rusage and rtprio. It no longer contains proc, session, pcred, ucred, procsig, vmspace, pstats, mtx, sigiolst, klist, callout, pasleep, or mdproc. If any of these changed in size, ps, w, fstat, gcore, systat, and top would all stop working. The new structure has over 200 bytes of unassigned space for future values to be added, yet is nearly 100 bytes smaller per entry than the structure that it replaced.
