Subject[PATCH 3.16.y-ckt 083/185] nfs: increase size of EXCHANGE_ID name string buffer
Date
3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

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

From: Jeff Layton <jlayton@poochiereds.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.
