From 4ee218cd67b385759993a6c840ea45f0ee0a8b30 Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Mon, 27 Mar 2006 01:17:48 -0800 Subject: [PATCH] [PATCH] dm: remove SECTOR_FORMAT We don't know what type sector_t has. Sometimes it's unsigned long, sometimes it's unsigned long long. For example on ppc64 it's unsigned long with CONFIG_LBD=n and on x86_64 it's unsigned long long with CONFIG_LBD=n. The way to handle all of this is to always use unsigned long long and to always typecast the sector_t when printing it.
