Ameer Hamza 4655bdd8ab ZTS: Fix L2ARC test reliability ... Disable depth cap (L2ARC_EXT_HEADROOM_PCT=0) in DWPD and multidev tests that rely on predictable marker advancement during fill and measurement. Rework multidev_throughput to verify sustained throughput across three consecutive windows instead of asserting an absolute rate. Use larger cache devices (8GB) to avoid frequent global marker resets (smallest_capacity/8), fill ARC before attaching caches to provide a stable evictable buffer pool, and lower write_max to 8MB/s to avoid exhausting data within the measurement period. Use destroy_pool (log_must_busy) instead of log_must zpool destroy to handle transient EBUSY during teardown. Remove l2arc_multidev_throughput_pos from the expected-fail list in zts-report.py.in.
