I'd agree with that.

Plus there's the PF_MEMALLOC thing which gives swapper-outers an extra
megabyte or two. If _any_ of these allocations are happening in process
context then they will benefit from this.

If all the allocations are happening at interrupt/softirq time then some
changes might be needed.

But I haven't been able to break it, using aix7xxx, with quite harsh
testing.
