Description

  • Also outside of the KOBJOPLOOKUP macro - which in turn is used by the code auto-generated for *.m - kobj_lookup_method(9) is useful; for example in back-ends or base class device drivers in order to determine whether a default method has been overridden. Thus, allow for the kobj_method_t pointer argument - used by KOBJOPLOOKUP in order to update the cache entry - of kobj_lookup_method(9), to be NULL. Actually, that pointer is redundant as it's just set to the same kobj_method_t that the kobj_lookup_method(9) function returns in the first place, but probably it serves to reduce the number of instructions generated for KOBJOPLOOKUP.
  • For the same reason, move updating kobj_lookup_{hits,misses} (if KOBJ_STATS is defined) from kobj_lookup_method(9) to KOBJOPLOOKUP. As a side-effect, this gets rid of the convoluted approach of always incrementing kobj_lookup_hits in KOBJOPLOOKUP and then in case of a cache miss, decrementing it in kobj_lookup_method(9) again.
