so that libmemstat can be used to view full memory statistics from kernel core dumps and /dev/mem. This is provided via a new query function, memstat_kvm_malloc(), which is also automatically invoked by memstat_kvm_all(). A kvm handle must be passed in. This will allow malloc(9)-specific code to be removed from vmstat(8).
