yes Jani, I know this.

But for some reasons I need to keep this one.

So I used gcc flag overriding

I'm in a situation where I have to choose between R15B03 with WX
or R16 without WX.
But maybe a fix will be found soon ? :) .
I suppose there is some needs on some system to limit
the fallocate to a 32 bit offset ...
