Subject: linux-next: build failure after merge of the final tree
 (device-mapper tree 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: In function 'ca_create':
drivers/md/persistent-data/dm-space-map-checker.c:96:3: error: implicit declaration of function 'vzalloc' [-Werror=implicit-function-declaration]
drivers/md/persistent-data/dm-space-map-checker.c:96:14: warning: assignment makes pointer from integer without a cast [enabled by default]
drivers/md/persistent-data/dm-space-map-checker.c: In function 'ca_destroy':
drivers/md/persistent-data/dm-space-map-checker.c:106:2: error: implicit declaration of function 'vfree' [-Werror=implicit-function-declaration]
drivers/md/persistent-data/dm-space-map-checker.c: In function 'ca_extend':
drivers/md/persistent-data/dm-space-map-checker.c:139:21: warning: initialization makes pointer from integer without a cast [enabled by default]

Caused by commit 30ebb0baeef5 ("If CONFIG_DM_DEBUG_SPACE_MAPS is enabled
and memory is fragmented and a") from the device-mapper tree.  Presumably
a missing include of vmalloc.h.

I have reverted that commit for today.
