ZFS supports O_RSYNC for read operations and when specified will ensure the same level of data integrity that O_DSYNC and O_SYNC provides for writes. O_RSYNC by itself has no effect so it must be combined with either O_DSYNC or O_SYNC. However, many platforms don't support O_RSYNC and have mapped O_SYNC to mean O_RSYNC within ZFS. This is incorrect and causes unnecessary calls to zil_commit. Only platforms which support O_RSYNC should implement the zil_commit functionality in the read code path.
