There are patches already to do the same for > riscv (pretty straight-forward after this series). Thanks, Catalin for getting these patches out. Please add my "Tested-by:" t= ag for the series: Tested-by: Isaac J. Manjarres With the first 11 patches, I observed a reduction of 18.4 MB in the slab memory footprint on my Pixel 6 device. After applying the rest of the patches in the series, I observed a total reduction of 26.5 MB in the slab memory footprint on my device. These are great results! --Isaac
