Hi Neil,

Today's linux-next build (powerpc ppc64_defconfig) failed like this:

ERROR: ".md_integrity_add_rdev" [drivers/md/multipath.ko] undefined!

Caused by commit 66f4f3f41f5c334f399e920b2aaad9b82514acda ("md: Push down
data integrity code to personalities") from the md-current and md trees.
Looks like md_integrity_add_rdev needs an EXPORT_SYMBOL.

I have used the version of the md-current and md trees from next-20090731
for today.
