Hi,

I am not sure if this patch is a fix or a hiding (or leads to more trouble at
all), so, could PLEASE anyone with knowledge about the code see over it?
Thanks :)

shrink_page_list() should not pass a private page to add_to_swap().
Is it a bug if the page is private when reaching this point? I do not think
so, because a few lines below is a condition where private pages are handled
legally.
