Martin Matuska dd801aa546 MFV r243013 and r243267: ... Import the zio nop-write improvement from Illumos. To reduce I/O, nop-write omits overwriting data if the checksum (cryptographically secure) of new data matches the checksum of existing data. It also saves space if snapshots are in use. It currently works only on datasets with enabled compression, disabled deduplication and sha256 checksums.
