[PATCH 3.12 113/123] nfs: increase size of EXCHANGE_ID name string buffer

From: Jiri Slaby
Date: Tue Aug 04 2015 - 10:45:53 EST


From: Jeff Layton <jlayton@xxxxxxxxxxxxxxx>

3.12-stable review patch. If anyone has any objections, please let me know.

===============

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.
