In this case, there is no point in logging the first case of error, as it will just be expected behavior. So there's really no way around explicitly annotating (ERR (EINVAL)) in place where it really matters, instead of changing the definition of -EINVAL itself or automatically converting check sites. > > and then change all code that does something like: > > if (err == -EINVAL) > to > if (err == -E_INVAL) > > Or have I misunderstood? -- Gabriel Krisman Bertazi
