Package: src:linux
Version: 3.16.7-ckt20-1+deb8u3
Followup-For: Bug #779628

I think this patch fixes this issue:

https://github.com/torvalds/linux/commit/627ccd20b4ad3ba836472468208e2ac4dfadbf03

It's included in this set which got merged in the 4.5 window.  See this
thread:

https://lkml.org/lkml/2015/12/30/331

It would be good to get this set into Stretch, and possibly a Jessie
point release too (IIRC, it will apply cleanly to the Jessie kernel).

Tim.
