From 1495f230fa7750479c79e3656286b9183d662077 Mon Sep 17 00:00:00 2001 From: Ying Han Date: Tue, 24 May 2011 17:12:27 -0700 Subject: vmscan: change shrinker API by passing shrink_control struct Change each shrinker's API by consolidating the existing parameters into shrink_control struct. This will simplify any further features added w/o touching each file of shrinker.
