Critical bug in quota

[Spacedust]

In linuxlib.php change the code to this:

        $totalinode = (int) (($disk / 100) + 1);

        $perblock = 1;
        $totalblock = $disk / $perblock;

        lxshell_return("setquota", "-u", $username, $totalblock, $totalblock, $totalinode, $totalinode, "-a");
}

This:

$perblock = getFSBlockSizeInKb();

Will assume the block is 4 kB and ex. instead of 10 GB user will get just 10/4=2,5 GB which is wrong !

setquota use $totalblock instead $disk (aka totalsize) and that why we must  '$totalblock = $disk / $perblock;'

But why we divide to /4 ?
