Subject: [PATCH 18/39] mm: pgrep: initialisation hooks
Date: Wed, 12 Jul 2006 16:40:27 +0200 [thread overview]
Message-ID: <20060712144027.16998.83825.sendpatchset@lappy> (raw)
In-Reply-To: <20060712143659.16998.6444.sendpatchset@lappy>
From: Peter Zijlstra <a.p.zijlstra@chello.nl>
Move initialization of the replacement policy's variables into the
implementation.
API:
initialize the policy:
void pgrep_init(void);
initialize the policies per zone data:
void pgrep_init_zone(struct zone *);
