Comment 1 Josh Boyer 2012-01-03 09:54:40 EST
Upstream discussion:


It seems Linus doesn't want to take the patches for 3.2 at all.  I'm somewhat inclined to agree for now.
Comment 2 Josh Boyer 2012-01-17 16:44:09 EST
The patches went into what will be 3.3, so they will be picked up when rawhide is rebased.

Paolo sent backported patches to the stable branches, but they missed the 3.1.10 cutoff (will be in 3.2.2 from what I saw).  I've applied them to the F15/F16 branches.
