This commit is tagged for stable but it looks like I missed it for the
3.5 kernel.  So, as Stefan already hinted, I'll queue it for the 3.5
kernel.

Btw, I can see this patch is in 3.8 kernel (and thus in Raring) but I
couldn't find in 3.2.  If you think its relevant for this kernel,
maybe its worth sending a request to stable mailing list.

Cheers,
