Hugo, I was interpreting your email of August 22nd as meaning that
the problem no longer existed in mainline:

https://marc.info/?l=linux-kernel&m=150343524911301&w=2

If my interpretation is correct, then this commit can wait until the
upcoming merge window.  As Ingo says, I can send patches to -stable
(and backporting is required, BTW).

If my interpretation is incorrect, please let me know what the situation
really is.

							Thanx, Paul
