I'm aware of that and removed the prefix knowingly. I see no
reason why it needs to be there. With static symbols now getting
prefixed by their file names in stack dumps and alike, I think we
should actually get rid of any such redundant static symbol name
prefixes (scheduler code being one of the biggest "user" of such).

Please clarify whether the R-b stands nevertheless, or whether
we need to have a longer debate first.
