This only happens in the NFS v3 code therefore 2.1.x is immune.

>Description:

When mounting a local directory via NFS to the same machine and doing any
operation involving the NFS mounted directory the machine simply freezes.

>How-To-Repeat:

mount -t nfs 127.0.0.1:/var /mnt
cd /mnt/tmp
dd if=/dev/zero of=foo count=10000

>Fix:

I have no idea.
