This change was necessary in order to pass the required parameters to
cache_update(). Doing without, I would have to pass nf_sock, cache, obj
and msgs fields additionally, and the number of parameters was already
quite big.
I would instead suggest to follow-up with a patch applying the change to
all other functions as well, though I'm not sure whether Eric might
make a voodoo doll which looks like me if I submit that now.

You mean if 'int err' is not used? But OK, in src/rule.c we have at
least three cases of 'return ret' and only two of 'return rc' (from my
patch) so I'll change that.
