Description

It was shown that lz4 is better than other compression algorithms ZFS has. L2Arc now use LZ4 compression and there is discussion about making lz4 a default algorithm. Yet, metadata is still compressed with old lzjb. We need to compress metadata with lz4 when the corresponding feature is enabled.
