Agreed. I wasn't seriously suggesting changing everywhere to be GFP_NOWARN. Perhaps I should be more explicit in what I'm saying here. The problem isn't just suspend trying to allocate memory. It's _ANYTHING_ that might be running trying to allocate memory while we're eating memory. (Remember that we don't just call shrink_all_memory, but also allocate that memory so other processes don't grab it and stop us making forward progress). As a result, they're going to scream when they can't allocate a page.
