As I mentioned on IRC, it is intentional that struct storage is
not 64-bit, there is no advantage of having storage-chunks larger than
a couple of GB and asking for it may cause the kernel to do more
than than good is.

I've cherry picked some of these changes, be aware that we should
use "%jd" printf formats, trusting "%ld" to do the right thing is
not productive.
