Subject: Don't assume read IO are always verifies if verify is enabled
X-Git-Tag: fio-1.33~2
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=715d2b3e02834232154604b91de1f9db53572a77;p=fio.git

Don't assume read IO are always verifies if verify is enabled

If it's a mixed read/write workload, we're likely just wanting to
verify the writes we do.
