Subject: [this_cpu_xx V3 14/19] this_cpu ops: Remove pageset_notifier
Date: Thu, 01 Oct 2009 13:40:47 -0400 [thread overview]
Message-ID: <20091001174122.224594195@gentwo.org> (raw)
In-Reply-To: <20091001174033.576397715@gentwo.org>
[-- Attachment #1: this_cpu_remove_pageset_notifier --]
[-- Type: text/plain, Size: 2270 bytes --]
Remove the pageset notifier since it only marks that a processor
exists on a specific node. Move that code into the vmstat notifier.
