Message-ID: <20190118094453.13773-3-shinichiro.kawasaki@wdc.com> (raw)
In-Reply-To: <20190118094453.13773-1-shinichiro.kawasaki@wdc.com>

Fio zbd zone mode is necessary for zoned block devices. Introduce the
helper function _have_fio_zbd_zonemode() to check that the installed
fio version supports the option --zonemode=zbd.
