Updated by Robert Mustacchi over 3 years ago

The problem here is unfortunately straightforward. What's happened is that the zfs_cmd_t used to be bitness neutral. However, the change for 6902 added a uint8_t to the zfs_cmd_t but didn't ensure that it was 32-bit / 64-bit clean. This then causes various members to now be off and in our tracing this showed that we were trying to pass a value of zero to holding a dataset snapshot.
