Title:
  Groovy update: v5.8.4 upstream stable release

Status in linux package in Ubuntu:
  Fix Committed
Status in linux source package in Groovy:
  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:

         v5.8.4 upstream stable release
