Thanks, I think you are the first to try to build blkback modular.

ERROR: "alloc_empty_pages_and_pagevec" [drivers/xen/blkback/blkbk.ko]
ERROR: "blk_put_queue" [drivers/xen/blkback/blkbk.ko] undefined!
ERROR: "free_empty_pages_and_pagevec" [drivers/xen/blkback/blkbk.ko] undefined!
ERROR: "blk_get_queue" [drivers/xen/blkback/blkbk.ko] undefined!
ERROR: "set_phys_to_machine" [drivers/xen/blkback/blkbk.ko] undefined!

The *_empty_pages_and_pagevec and set_phys_to_machine are probably fair
game for an EXPORT_SYMBOL_GPL. The two blk subsystem ones are
suspicious, the fact that they aren't already exported suggests there is
another API we should be using.
