This commit introduces per-sublist persistent markers that eliminate redundant tail scanning between L2ARC iterations, providing significant CPU efficiency improvements. Markers are pre-allocated during device initialization and properly cleaned up during device removal. The implementation uses conditional behavior based on device capacity: small devices (capacity < arc_c) retain original HEAD/TAIL scanning based on ARC warmup state, while large devices (capacity >= arc_c) use the persistent marker approach for optimal CPU efficiency.
