Hi Greg,

After merging the usb tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

ERROR: "usb_stor_dbg" [drivers/usb/storage/ums-usbat.ko] undefined!

Caused by commit 75b9130e8af6 ("usb: storage: Add usb_stor_dbg, reduce
object size").  Please build test such infrastructure patches with and
without MODULES ...

I have used the usb tree from next-20130417 for today.
