Subject: Start of support for auto-starting the backend
X-Git-Tag: gfio-0.1~279
X-Git-Url: https://git.kernel.dk/?p=fio.git;a=commitdiff_plain;h=b9f3c7ed703f0f94476c5d9123034a45a4936517;hp=8663ea652b8ca7a368b39ef97e991180edebb57f

Start of support for auto-starting the backend

When running fio as a client only, you need the backend running
on the system. Start adding support for letting gfio auto-fork
the backend, if it isn't already running.
