Title:
  Disco update: upstream stable patchset 2019-10-16

Status in linux package in Ubuntu:
  Confirmed
Status in linux source package in Disco:
  Fix Committed

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 following upstream
         stable patches should be included in the Ubuntu kernel:

         upstream stable patchset 2019-10-16

                Ported from the following upstream stable releases:
                        v4.19.77, v5.2.19
