From 6b3df0d7a5e85ad2afd3eecc50e2dee59e876ae8 Mon Sep 17 00:00:00 2001 From: Jonathan Brassow Date: Fri, 19 Oct 2007 22:47:57 +0100 Subject: [PATCH] dm log: split suspend There are now two phases to a suspend in device-mapper - presuspend and postsuspend. This patch removes the single 'suspend' in the logging API and replaces it with 'presuspend' and 'postsuspend' functions to align it better with core device-mapper. A subsequent patch will make use of 'presuspend'.
