[PATCH 0/3] nfsstat: Fixing and improving the new --sleep and --list options

[Steve Dickson <SteveD@redhat.com>]

Using the new --sleep and --list options to nfsstats,
I found a server side bug and an annoyance when particular
protocols where specified. 

When the --sleep options as used with a particular protocol
option (i.e. -2, -3 or -4) and there was no traffic, blank
lines were being echoed to the screen causing useful data
to be scrolled of the screen.

Also with the --sleep option, the server stats were not
being updated which meant the same values would be echoed
again and again when there was not new server traffic.

Finally when using the --sleep and/or --list options, zero 
stats will not be displayed. I found it much more useful to
show what happen instead of showing what did not happen. 
Plus not showing zero stats makes the --list much easier to 
read and digest as well as keeping useful data from scrolling
off the screen.

The server side bug was the fact --list didn't on server
stats. The client stats were being check when the server
stats should have been.
