Alexander Motin 97c1fb6ad5 ARC: Notify dbuf cache about target size reduction ... ARC target size might drop significantly under memory pressure, especially if current ARC size was much smaller than the target. Since dbuf cache size is a fraction of the target ARC size, it might need eviction too. Aside of memory from the dbuf eviction itself, it might help ARC by making more buffers evictable.
