+l2arc_meta_percent
+~~~~~~~~~~~~~~~~~~
+
+Percent of ARC size allowed for L2ARC-only headers.
+Since L2ARC buffers are not evicted on memory pressure, too large amount of
+headers on system with irrationaly large L2ARC can render it slow or unusable.
+This parameter limits L2ARC writes and rebuild to achieve it.
