Subject: init: abort write and trim jobs when --readonly option is present
X-Git-Tag: fio-3.8~27^2~3
X-Git-Url: https://git.kernel.dk/?p=fio.git;a=commitdiff_plain;h=c0e9a23844dd78a0dd07ab72f59114089e639e74;hp=1cce3c66140206967462f85646a50b0065da87e9

init: abort write and trim jobs when --readonly option is present

Check for conflicts between --readonly and the job's data direction
in fixup_options(). rw_verify() in options.c only detects this
conflict if --readonly precedes --readwrite on the command line.
