I've run some benchmarking and I've determined most of the perf gains I
observed can be isolated to a subset of the changes in this series.
Therefore I've repackaged it in a single patch, which also considers
other feedback gathered in this series:

https://lore.kernel.org/lkml/20251120101955.968586-1-sieberf@amazon.com/T/#u

I've also included benchmark test results. This current patch series can
be cancelled in favor of the new patch.
