Subject: [PATCH 3.2 037/110] nfs: increase size of EXCHANGE_ID name string
 buffer

3.2.71-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Jeff Layton <jlayton@...chiereds.net>

commit 764ad8ba8cd4c6f836fca9378f8c5121aece0842 upstream.

The current buffer is much too small if you have a relatively long
hostname. Bring it up to the size of the one that SETCLIENTID has.
