No. For any directory it doesn't work.

There is a stranger behavior. If I mount the parent directory of the 
export like /home/test/huge/temp_small or /home/test/huge (when 
/home/test/huge/whatever is exported), it mounts and only the exported 
directory is accessible/seen. However all_squash flag does not appear to 
be working with /home/test/huge/temp_small; I cant access 
/home/test/huge/temp_small/subdir as root.

But it appears to be working for localhost.

The inodes are 32 bit. e.g. 297618, 264250, 280589 etc...

On one end I'm running the server on 3.17 and the client on 3.10.
