Sorry for the noise, here's another oddity, same setup (client & server 
running 3.11-rc5):

$ find /mnt/nfs/usr/share/ -name getopt.awk -ls
 25072    4 -rw-r--r--   1 root     root         2237 Mar 16 04:46 /mnt/nfs/usr/share/awk/getopt.awk
 25072    4 -rw-r--r--   1 root     root         2237 Mar 16 04:46 /mnt/nfs/usr/share/awk/getopt.awk
 25072    4 -rw-r--r--   1 root     root         2237 Mar 16 04:46 /mnt/nfs/usr/share/awk/getopt.awk
 25072    4 -rw-r--r--   1 root     root         2237 Mar 16 04:46 /mnt/nfs/usr/share/awk/getopt.awk
 25072    4 -rw-r--r--   1 root     root         2237 Mar 16 04:46 /mnt/nfs/usr/share/awk/getopt.awk
 25072    4 -rw-r--r--   1 root     root         2237 Mar 16 04:46 /mnt/nfs/usr/share/awk/getopt.awk
 25072    4 -rw-r--r--   1 root     root         2237 Mar 16 04:46 /mnt/nfs/usr/share/awk/getopt.awk
 25072    4 -rw-r--r--   1 root     root         2237 Mar 16 04:46 /mnt/nfs/usr/share/awk/getopt.awk
 25072    4 -rw-r--r--   1 root     root         2237 Mar 16 04:46 /mnt/nfs/usr/share/awk/getopt.awk
 25072    4 -rw-r--r--   1 root     root         2237 Mar 16 04:46 /mnt/nfs/usr/share/awk/getopt.awk

It's the same file, but gets reported 10 times! Hence the error when 
trying to tar(1) the directory:

$ tar -cf - /mnt/nfs/usr/share/awk/ > /dev/null
tar: Removing leading `/' from member names
tar: /mnt/nfs/usr/share/awk/: Cannot savedir: Too many levels of symbolic links
tar: Exiting with failure status due to previous errors

On the server:

$ find /mnt/disk/usr/share/ -name getopt.awk -ls
 25072    4 -rw-r--r--   1 root     root         2237 Mar 16 04:46 /mnt/disk/usr/share/awk/getopt.awk

So, is "JFS && NFS" really br0ken and nobody noticed?
