A bit off topic but this reminded me of these patches:

http://patchwork.ozlabs.org/patch/206753/
http://patchwork.ozlabs.org/patch/208252/

which never got merged. Is there a chance that these fixes get merged 
sometimes or is there an explanation why it won't be fixed? As far as I 
remember the patches were reviewed and multiple versions were proposed but 
at the end no decision was reached on which one to merge and it was just 
left uncorrected.
