From 2b2c7b1db51a8fcb306b6306b269a9d4ae58ffdf Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Wed, 6 Apr 2011 22:25:38 +0300 Subject: [PATCH] cpu: add set_memory flag to request dirty logging Pass the flag to all cpu notifiers, doing nothing at this point. Will be used by follow-up patches. Signed-off-by: Michael S.
