[Xen-devel] [PATCH] xen-tmem-list-parse: fix ugly parse output

[Dan Magenheimer <dan.magenheimer@xxxxxxxxxx>]

Hmmm... It appears I never posted the corrected version of this patch
so it never made it upstream.  See:

http://lists.xen.org/archives/html/xen-devel/2011-11/msg00587.html 
http://lists.xen.org/archives/html/xen-devel/2011-11/msg02145.html 

It would be good if this very minor fix was also applied to 4.2
(and, if possible, 4.1).

Thanks,
Dan

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

The program xen-tmem-list-parse parses the output of xm/xl tmem-list
into human-readable format.  A missing NULL terminator sometimes
causes garbage to be spewed where the two-letter pool type
should be output.
