in RTFREE_LOCKED:
if ((_rt)->rt_refcnt <= 1) \
rtfree(_rt); \
in rtfree:
RT_REMREF(rt);
if (rt->rt_refcnt > 0) {
printf("%s: %p has %lu refs\n", __func__, rt, rt->rt_refcnt);
goto done;
in RT_REMREF:
#define RT_REMREF(_rt) do { \
RT_LOCK_ASSERT(_rt); \
KASSERT((_rt)->rt_refcnt > 0, \
("bogus refcnt %ld", (_rt)->rt_refcnt)); \
(_rt)->rt_refcnt--; \
Something is clearly holding a reference to an rtentry. Perhaps the printf should go under #ifdef DIAGNOSTIC.
