Hi,

great timing :) I just sent the pull request for 4.1 out yesterday :)
But thanks for spotting and fixing it. 
Found bugs are good bugs, and fixed ones are even better.

Are kernels < 4.0 also affected or was this code introduced in 4.0 ?

How critical is the mentioned 'critical failure' ? What will happen?
How often does it happen?  

If this thing is big enough and kernels < 4.0 are not affected we can try to 
get it into 4.0 still, so no stable. (but I still need the backport :) )


If it won't hit 4.0 then backport to 4.0.1 is needed,
which will be sent to stable@...
with the upstream commit mentioned.

Thanks,
Peter
