Hi Neil,

After merging the md tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

ERROR: ".bitmap_resize" [drivers/md/raid456.ko] undefined!
ERROR: ".bitmap_resize" [drivers/md/raid10.ko] undefined!

Caused by commit 89efe2ab3a8c ("md/bitmap: add bitmap_resize function to
allow bitmap resizing") and followups.

I have used the md tree form next-20120418 for today.
