[PATCH 0/4] Add support for IO priority hints

[Damien Le Moal <dlemoal@kernel.org>]

Linux kernel 6.5 will add support for IO priority hints, which can be
used for now to specify a command duration limit for block devices
supporting this feature.

This patch series extends fio IO priority options and adds new options
to allow users to specify IO priority hints.

Damien Le Moal (4):
  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
