From: Jonathan Brassow Date: Fri, 19 Oct 2007 21:47:57 +0000 (+0100) Subject: dm log: split suspend X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6b3df0d7a5e85ad2afd3eecc50e2dee59e876ae8;p=linux-beck.git 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'.
