looks OK, but the whole situation with that and often also btrfs is sometimes
a bit weird in subtle ways, so a quick look from you wolfgang would be appreciated.

Also, one style nit inline.

I'd actually prefer the rustfmt style for wrapping simple lists of parameters, in that
case the following should make it happy, well theoretically as it would choke on perl,
as lots others do:

return PVE::Storage::DirPlugin::update_volume_attribute(
    $class, $scfg, $storeid, $volname, $attribute, $value);

And if that'd still require to much width it'd go one param per line.
I'll see that I update the style guide with that.
