Subject: [RFC 5/8] Drop nr_free_pages_pgdat()
Date: Thu, 25 Jan 2007 21:42:19 -0800 (PST) [thread overview]
Message-ID: <20070126054219.10564.13523.sendpatchset@schroedinger.engr.sgi.com> (raw)
In-Reply-To: <20070126054153.10564.43218.sendpatchset@schroedinger.engr.sgi.com>
Get rid of nr_free_pages_pgdat()
Function is unnecessary now. We can use the summing features of the ZVCs to
get the values we need.
