Subject: linux-next: build failure after merge of the final tree
 (device-mapper and moduleh trees related)

Hi all,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/md/persistent-data/dm-space-map-checker.c:386:1: warning: data definition has no type or storage class [enabled by default]
drivers/md/persistent-data/dm-space-map-checker.c:386:1: warning: type defaults to 'int' in declaration of 'EXPORT_SYMBOL_GPL' [-Wimplicit-int]
drivers/md/persistent-data/dm-space-map-checker.c:386:1: warning: parameter names (without types) in function declaration [enabled by default]
drivers/md/persistent-data/dm-space-map-checker.c:417:1: warning: data definition has no type or storage class [enabled by default]
drivers/md/persistent-data/dm-space-map-checker.c:417:1: warning: type defaults to 'int' in declaration of 'EXPORT_SYMBOL_GPL' [-Wimplicit-int]
drivers/md/persistent-data/dm-space-map-checker.c:417:1: warning: parameter names (without types) in function declaration [enabled by default]

Caused by commit 661ae8a9604f ("The persistent-data library offers a
re-usable framework for the storage") interacting with the module.h split
up.

I added this patch for today:

Subject: [PATCH] device-mapper: using EXPORT_SYBOL in dm-space-map-checker.c
