That's a good question.  I'm not sure what you're referring to in 2.6.27
-- can you give more details about what you heard or read?  It would
also help me to know a bit more about what you are trying to achieve.

Please consider re-sending your question to systemtap@sourceware.org,
so other experts can also help, and other users can see the answers.

Thanks,
