Subject: common: Introduce _have_fio_zbd_zonemode() helper function
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=3095d6a0e10085459e6116e04df59e40dd39d224;p=users%2Fsagi%2Fblktests.git

common: Introduce _have_fio_zbd_zonemode() helper function

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.
