This is annoying to users as OOMs are a fact\nof life, and we pretty much expect network Rx to hit page allocation\nfailures during OOM. Make page pool add GFP_NOWARN for ATOMIC allocations\nby default."

Although globally rate-limited, the resulting persistent disruption can become severe in a reasonable network-appliance deployment."
