Subject: Add verify hook to options
X-Git-Tag: fio-1.29-rc1~5
X-Git-Url: https://git.kernel.dk/?p=fio.git;a=commitdiff_plain;h=70a4c0c8417bba7c2e1e9a384b9acf226f5b9782

Add verify hook to options

This allows us to individually verify options, instead of having
a big function that attempts to fix things up.
