Tom Caputi df583073eb Do not iterate through filesystems unnecessarily ... Currently, when attempting to list snapshots ZFS may do a lot of extra work checking child datasets. This is because the code does not realize that it will not be able to reach any snapshots contained within snapshots that are at the depth limit since the snapshots of those datasets are counted as an additional layer deeper. This patch corrects this issue. In addition, this patch adds the ability to do perform the commands: $ zfs list -t snapshot <dataset> $ zfs get -t snapshot <prop> <dataset> as a convenient way to list out properties of all snapshots of a given dataset without having to use the depth limit.
