Hmm. Is this a new problem to 2.6.29?

The patch is pretty big (certainly _way_ over the official -stable limit), 
and I don't know how critical or new this bug was. I doubt it has gotten 
much testing in the development branch either, yet.

So please convince me that this shouldn't wait a bit, or at least point me 
to the problem reports to convince me that the size limit should be 
ignored.
