Comment 17 for bug 1313279

I'm way out of date on this, but that patch looks like it was committed into the Linux kernel in Mach 2015:

https://github.com/torvalds/linux/commit/227a4fd801c8a9fa2c4700ab98ec1aec06e3b44d

... which would suggest that it would have appeared "in the wild" with 3.19.2 or thereabouts?

Even if my timeline isn't completely accurate, and if that patch fixes the problem, then it should be ancient history by your 4.4.0 kernel.
