/*

  WARNING/NOTE: whenever you want to add an option here you need to
  either

  * mark it as an optional one with `?` suffix,
  * or make sure it works for all the versions in nixpkgs,
  * or check for which kernel versions it will work (using kernel
    changelog, google or whatever) and mark it with `versionOlder` or
    `versionAtLeast`.

  Then do test your change by building all the kernels (or at least
  their configs) in Nixpkgs or else you will guarantee lots and lots
  of pain to users trying to switch to an older kernel because of some
  hardware problems with a new one.
