Two pid_t fields are added by carving 8 bytes from ki_sparestrings (46 -> 38), restoring KI_NSPARE_INT to 2 and keeping sizeof(struct kinfo_proc) unchanged: ki_reaper: PID of the owning reaper process ki_reapsubtree: PID of the direct child of the reaper that roots the subtree the process belongs to fill_kinfo_proc_pgrp() populates both fields under proctree_lock. kvm_proclist() is updated for crash dump consumers. The freebsd32 compat struct and freebsd32_kinfo_proc_out() are updated accordingly.
