docs: // Mkdev is used to build the value of linux devices (in /dev/) which specifies major
  // and minor number of the newly created device special file.
  // Linux device nodes are a bit weird due to backwards compat with 16 bit device nodes.
  // They are, from low to high: the lower 8 bits of the minor, then 12 bits of the major,
  // then the top 12 bits of the minor.
