Remove btrfs_qgroup_inherit_add_copy() and the command line interface. This was designed to add a pair of source/destination qgroups into btrfs_qgroup_inherit structure, so that rfer/excl numbers would be copied from the source qgroup into the destination one. This behavior has been intentionally hidden since 2016, as such copy will cause qgroup inconsistent immediately and a rescan would reset whatever numbers copied anyway. Now we're going to reject the copy behavior from kernel, there is no need to keep those hidden (and already disabled for "subvolume create") case. Remove btrfs_qgroup_inherit_add_copy() call, and cleanup the undocumented options. Signed-off-by: Qu Wenruo <wqu@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
