  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:
  
         v5.4.202 upstream stable release
         from git://git.kernel.org/
  
- dm: remove special-casing of bio-based immutable singleton target on NVMe
