Hi Stephen!

Hmm, we must not avoid shrink_mmap() to run. So I see plain wrong to set
the PF_MEMALLOC before call __get_free_pages(). Very cleaner to use
GFP_ATOMIC to achieve the same effect btw ;).

Now I am too tired to follow the other part of your email (I'll read
tomorrow, now it's time to sleep for me... ;).

Forget to tell, did you have comments about the FreeAfter() stuff? It made
sense to me (looking at page_io if I remeber well) but I have not
carefully reread it yet after Linus's comments on it.
