Alexander Motin cbd8f5b759 Few microoptimizations to dbuf layer ... Move db_link into the same cache line as db_blkid and db_level. It allows significantly reduce avl_add() time in dbuf_create() on systems with large RAM and huge number of dbufs per dnode. Avoid few accesses to dbuf_caches[].size, which is highly congested under high IOPS and never stays in cache for a long time. Use local value we are receiving from zfs_refcount_add_many() any way. Remove cache_size_bytes_max bump from dbuf_evict_one(). I don't see a point to do it on dbuf eviction after we done it on insertion in dbuf_rele_and_unlock().
