This inode can only be freed while N1 doing the orphan scan work. However, N1 may skip orphan scan for several times because other nodes may do the work earlier. In our tests, it may take 1 hour on 4 nodes cluster and this will cause bad user experience. So we think the inode should be freed when i_count becomes zero to avoid such circumstances.
