Having "ret" be a bool type works for everything except
ret = funcs->atomic_check(). The other functions all return zero on
error but ->atomic_check() returns negative error codes. We want to
propagate the error code but instead we return 1.
I found this bug with static analysis and I don't know if it affects
run time.
