No page allocation failures after 33 hours of uptime under normal
desktop workload with memory pressure (64GB RAM, btrfs + zram swap,
Chrome with many tabs, AMD GPU).
Previously without this patch, I was seeing failures from both
kswapd0/btrfs and chrome/amdgpu callers within 10 hours.
Kernel: 7.0.0-rc1 (commit 7dff99b35460 + this patch)
Hardware: ASUS ROG STRIX B650E-I, AMD Ryzen, 64GB RAM
