   dwisimplifies tidies up patch 5.
 - Added Niklas review tag to patch 1

Changes from v1:
 - Added patch 1
 - Addressed Niklas comments

Damien Le Moal (6):
  os-linux: Cleanup IO priority class and value macros
  cmdprio: Introduce generic option definitions
  os-linux: add initial support for IO priority hints
  options: add priohint option
  cmdprio: Add support for per I/O priority hint
  stats: Add hint information to per priority level stats
