commit c761709ad3abb9c36a68c269f78118bf49d79639
Author: Chuck Lever <chuck.lever at oracle.com>
Date: Mon Jun 23 12:52:33 2008 -0400
The "mountstats" utility is a Python program that extracts and displays NFS
client performance information from /proc/self/mountstats.
Note that if mountstats is named 'ms-nfsstat' or 'ms-iostat' it offers
slightly different functionality. It needs two man pages and the install
script should provide both commands by installing the script and providing the
other command via a symlink.

--- NEW FILE nfs-utils-1.1.2-nfsstat-counters.patch ---
commit 5be04020788598cb811e51c4b1342cf0796cbb65
Author: Jeff Layton <jlayton at redhat.com>
Date: Mon Jun 23 07:21:52 2008 -0400
The nfsstat program reads /proc/net/rpc/* files to gets info about
calls. This info is output as unsigned numbers (at least on any
relatively recent kernel). When nfsstat prints these numbers, they are
printed as signed integers. When the call counters reach 2^31, things
start being printed as negative numbers.
This patch changes nfsstat to read and print all counters as unsigned
integers. Tested by hacking up a kernel to initialize call counters to
2^31+1.
Thanks to Takafumi Miki for the initial version of this patch.
