This doesn't seem to bear any resemblence to the subject line.

This isn't explained in the commit. You explain why it should return
true or false, but you don't explain why converting this from returning
0, aka false, to returning true is necessary.

At least this partially matches the subject line but it looks unrelated
to the other changes.
