That should be fixed. Are there any existing memory pools that could be used
instead? I (And I think everybody) is all for using the existing APIs if they
can do the job. I was lookign a bit at the dmapool code, but that requires something
we don't have - the 'struct device'. We could manufacture a fake one, but that just
stinks of hack.
It [pagepool] also should use the shrinker API I think.
