are not allowed to execute concurrently. If this field specifies unrestricted re-ordering
(0001b), concurrent I/O execution is allowed.
2. Fully supported and temporary fields are underlined. Unsupported fields are not
underlined. The PS bit is underlined, meaning it will be set on a MODE SENSE
command, since the page is savable
