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