I agree with your patch.
The following comment is for possible improvements. What about using
if (__builtin_expect(__ret == 0, 0))
That gives a hint to the compiler that the branch is expected to be
taken very unfrequently, and it should make scheduling accordingly.
In general, I would like to see us starting using use __builtin_expect()
at places where we do checks for limits cases. Thoughts?
