Subject: backend: don't complain about no IO done for create_only=1
X-Git-Tag: fio-3.2~63
X-Git-Url: https://git.kernel.dk/?p=fio.git;a=commitdiff_plain;h=f7c9bfd57232c6e11623d741be340d32f796c726

backend: don't complain about no IO done for create_only=1

It's expected that we didn't actually run any IO, if the user
asked for just file creation.

Fixes: 48366f3a92cb ("Don't silently terminate td when no I/O performed due to error")
