Subject: [PATCH 06/14] Add per zone counters to zone node and global VM statistics
Date: Thu, 8 Jun 2006 16:03:10 -0700 (PDT) [thread overview]
Message-ID: <20060608230310.25121.77780.sendpatchset@schroedinger.engr.sgi.com> (raw)
In-Reply-To: <20060608230239.25121.83503.sendpatchset@schroedinger.engr.sgi.com>
Extend per node and per zone statistics by printing the additional counters now available.
- Add new counters to per node statistics
- Add new counters to per zone statistics
- Provide an array describing zoned VM counters
