If any of them have been fixed already, please let us know.

If you know of any other unresolved regressions from 3.0 and 3.1, please let us
know either and we'll add them to the list.  Also, please let us know if any of
the entries below are invalid.

Andrea's patch already fixes this issue, which was reported first by
Jiri Slaby. https://lkml.org/lkml/2011/11/11/93
I remember Andrew Morton taking this patch in his -mm tree. But it is
not in mainline yet. So can we consider this closed or not?

Thanks,
Srivatsa S. Bhat
