Hmm, you're right.  But they _are_ non-waiting allocations.  The "mode=0x10000"
seems to be common which is __GFP_NOMEMALLOC, which is even less likely to
succeed than GFP_ATOMIC.

Some of those are coming from mempool allocations, and mempool adds
__GFP_NOWARN to the flags, but that seems to get cleared somewhere.

The problem is there's so many reports in one bug, and there's not much
commonality between them, except that all of them are atomic allocations.

I'll try to sort them out and find some pattern.
