   69  * KERN_PROC subtype ops return arrays of selected proc structure entries:
   70  *
   71  * This struct includes several arrays of spare space, with different arrays
   72  * for different standard C-types.  When adding new variables to this struct,
   73  * the space for byte-aligned data should be taken from the ki_sparestring,
   74  * pointers from ki_spareptrs, word-aligned data from ki_spareints, and
   75  * doubleword-aligned data from ki_sparelongs.  Make sure the space for new
   76  * variables come from the array which matches the size and alignment of
   77  * those variables on ALL hardware platforms, and then adjust the appropriate
   78  * KI_NSPARE_* value(s) to match.
   79  *
   80  * Always verify that sizeof(struct kinfo_proc) == KINFO_PROC_SIZE on all
   81  * platforms after you have added new variables.  Note that if you change
   82  * the value of KINFO_PROC_SIZE, then many userland programs will stop
   83  * working until they are recompiled!
   84  *
   85  * Once you have added the new field, you will need to add code to initialize
   86  * it in two places: function fill_kinfo_proc in sys/kern/kern_proc.c and
   87  * function kvm_proclist in lib/libkvm/kvm_proc.c .
