Subject: Make fio include the git version in the version output
X-Git-Tag: gfio-0.1~66
X-Git-Url: https://git.kernel.dk/?p=fio.git;a=commitdiff_plain;h=3d43382c7864753728b181ac356222d67bdd4a3f;ds=sidebyside

Make fio include the git version in the version output

Makes it easier in bug reporting, don't have to ask people what
they are running...

Here's to you, Kep.
