Looks good.

A side note, I can see that Serial is the only GC that calls its file "serialMemoryPools.hpp", while all other GCs call it "..MemoryPool.hpp".

$ find src/hotspot/share/gc -name "*MemoryPool*.hpp"
src/hotspot/share/gc/epsilon/epsilonMemoryPool.hpp
src/hotspot/share/gc/g1/g1MemoryPool.hpp
src/hotspot/share/gc/parallel/psMemoryPool.hpp
src/hotspot/share/gc/serial/serialMemoryPools.hpp
src/hotspot/share/gc/shenandoah/shenandoahMemoryPool.hpp
