Some of ZFS ACLs doesn't work as expected

[Pavel Bychykhin]

Dear community!

After my experiments with ZFS, I concluded, that permissions 
"delete_child" and "delete" are ignored.
For the create/update/delete operation a list of "rwxp" 
(read_data/write_data/execute/append_data) is fully sufficient.

No need to specify the "delete_child" and "delete" permissions at all, 
or I don't understand something?

Thanks in advance.
