Tom Caputi b1d217338a Raw receives must compress metadnode blocks ... Currently, the DMU relies on ZIO layer compression to free LO dnode blocks that no longer have objects in them. However, raw receives disable all compression, meaning that these blocks can never be freed. In addition to the obvious space concerns, this could also cause incremental raw receives to fail to mount since the MAC of a hole is different from that of a completely zeroed block. This patch corrects this issue by adding a special case in zio_write_compress() which will attempt to compress these blocks to a hole even if ZIO_FLAG_RAW_ENCRYPT is set. This patch also removes the zfs_mdcomp_disable tunable, since tuning it could cause these same issues.
