The point here is that what is being done is not obvious from either the
function
name or quickly reading the code. A comment would really help.

No. you're right, my brain was flipped.

Hmm? On which line?
148 static boolean_t
149 is_correct_event(const char *fmri, const scf_propertygroup_t *pg,
150 const boolean_t isrpc)
151 {
152 char *pg_name, *value, *state = NULL;
153 scf_value_t *v;
154 boolean_t ret = B_FALSE, in_maintenance = B_FALSE;
155
156 if ((pg_name = umem_alloc(max_scf_value_size, UMEM_DEFAULT))
157 == NULL)
158 goto out;
...
268 out:
269 if (state)
270 free(state);
271
272 umem_free(pg_name, max_scf_value_size);
273 scf_value_destroy(v);
274
275 return (ret);
276 }

In the absence of a man page for _scf_notify_wait(), it might be
worthwhile adding
a commit here that mentions the behaviour.
