Subject: t/zbd: avoid looping on invalid command line options
X-Git-Tag: fio-3.26~14
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=1cae9fe4e16b807ae92658a82c747ffcd02dd174;hp=b13fd959ef8af944a5066976e90d80043bfa0add;p=fio.git

t/zbd: avoid looping on invalid command line options

t/zbd/test-zbd-support loops indefinitely if an unrecognized option
is specified in the command line. Add a switch case to display usage
and exit the script.
