    compile  lib/nvpair.o
    /u/NetBSD/src/sys/external/bsd/libnv/dist/nvpair.c: In function 'nvpair_create_stringv':
    /u/NetBSD/src/sys/external/bsd/libnv/dist/nvpair.c:1220:2: error: implicit declaration of function 'kmem_free'; did you mean 'nv_free'? [-Werror=implicit-function-declaration]
      kmem_free(str, len+1);
      ^~~~~~~~~
    nv_free
    cc1: all warnings being treated as errors
