Subject: [PATCH 1/39] mm: disuse activate_page()
Date: Wed, 12 Jul 2006 16:37:11 +0200 [thread overview]
Message-ID: <20060712143711.16998.38962.sendpatchset@lappy> (raw)
In-Reply-To: <20060712143659.16998.6444.sendpatchset@lappy>
From: Marcelo Tosatti <marcelo.tosatti@cyclades.com>
Get rid of activate_page() callers.
Instead, page activation is achieved through mark_page_accessed()
interface.
