Ameer Hamza 62ca8f721b L2ARC: Scan-based depth cap for persistent markers ... With persistent markers and inclusive scanning, the marker traverses the entire ARC state across many feed cycles, writing buffers far from the tail that may no longer be relevant. Track cumulative bytes scanned per pass in l2arc_ext_scanned. When scans reach l2arc_ext_headroom_pct (default 25%) of the ARC state size, reset the pass markers to the tail via lazy reset flags. This keeps markers focused on the tail zone where buffers soon to be evicted have the most value for L2ARC.
