Bug Description

SRU Justification

Impact:
   The upstream process for stable tree updates is quite similar
   in scope to the Ubuntu SRU process, e.g., each patch has to
   demonstrably fix a bug, and each patch is vetted by upstream
   by originating either directly from a mainline/stable Linux tree
   or a minimally backported form of that patch. The 4.4.127 upstream
   stable stable patch set is now available. It should be included
   in the Ubuntu kernel as well.

git://git.kernel.org/
