The introduction of ARC multilists made L2ARC writing quite random, depending on whether it found something to write in a randomly selected sublist. This created inconsistent write patterns and poor utilization of available sublists leading to uneven cache population. This commit replaces random selection with systematic scanning across all sublists within each burst. Fair headroom distribution ensures even-depth traversal across all sublists until the target write size is reached. Round-robin processing with random starting points eliminates sequential bias while maintaining predictable write behavior. The systematic approach provides consistent L2ARC filling patterns and better utilization of available ARC data across all sublists.
