Bug description:
  SRU Justification

         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 2020-03-10

                  Ported from the following upstream stable releases:
                          v4.19.103, v5.4.19

         from git://git.kernel.org/
