/*
Disk inode deletion may be heavily delayed when one node unlink a file after the same dentry is freed on another node(say N1) because of memory shrink but inode is left in memory. 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 it hurts the user experience. So we think the inode should be freed after the data flushed to disk when i_count becomes zero to avoid such circumstances.
