Subject: [PATCH 01/34] mm: kill-page-activate.patch
Date: Wed, 22 Mar 2006 23:31:50 +0100 [thread overview]
Message-ID: <20060322223118.12658.36826.sendpatchset@twins.localnet> (raw)
In-Reply-To: <20060322223107.12658.14997.sendpatchset@twins.localnet>
From: Marcelo Tosatti <marcelo.tosatti@cyclades.com>
Get rid of activate_page() callers.
Instead, page activation is achieved through mark_page_accessed()
interface.
