That does fix the build errors.  Thanks.

Here is a more complete patch with a patch description and S-O-B.
I would have put your S-O-B in it but you didn't include one.
Feel free to add yours now.

From: Randy Dunlap <rdunlap@...radead.org>

Drop percpu_ida.o from lib-y since it is also listed in obj-y
and it doesn't need to be listed in both places.

Move percpu-refcount.o from lib-y to obj-y to fix build errors
in target_core_mod:

ERROR: "percpu_ref_cancel_init" [drivers/target/target_core_mod.ko] undefined!
ERROR: "percpu_ref_kill_and_confirm" [drivers/target/target_core_mod.ko] undefined!
ERROR: "percpu_ref_init" [drivers/target/target_core_mod.ko] undefined!
