67  * KERN_PROC subtype ops return arrays of selected proc structure entries:
68  *
69  * This struct includes several arrays of spare space, with different arrays
70  * for different standard C-types.  When adding new variables to this struct,
71  * the space for byte-aligned data should be taken from the ki_sparestring,
72  * pointers from ki_spareptrs, word-aligned data from ki_spareints, and
73  * doubleword-aligned data from ki_sparelongs.  Make sure the space for new
74  * variables come from the array which matches the size and alignment of
75  * those variables on ALL hardware platforms, and then adjust the appropriate
76  * KI_NSPARE_* value(s) to match.
77  *
78  * Always verify that sizeof(struct kinfo_proc) == KINFO_PROC_SIZE on all
79  * platforms after you have added new variables.  Note that if you change
80  * the value of KINFO_PROC_SIZE, then many userland programs will stop
81  * working until they are recompiled!
82  *
83  * Once you have added the new field, you will need to add code to initialize
84  * it in two places: function fill_kinfo_proc in sys/kern/kern_proc.c and
85  * function kvm_proclist in lib/libkvm/kvm_proc.c .
