This is from a patch added to linux-next only yesterday and was
reported by Randy Dunlap from his overnight build testing.

Missing an ifdef:-( Sorry about that. Better drop those two patches for now
then.

That's my fault, module_refcount can only be used ifCONFIG_MODULE_UNLOAD defined according to <linux/module.h>,
So now maybe we can add a null macro to module_refcount ifCONFIG_MODULE_UNLOAD undefined?

Do we even need the test at all?

So you mean add "#ifdef CONFIG_MODULE_UNLOAD ..." to dm-target.c? Ican do that, but I really don't know a better solution withoutconditional compiling?

I mean under what set of circumstances could the test of the module refcount
here fail, and if the test was simply removed are there any cases where that
would matter?

The fact that module_refcount may be undefined is an indicator that this
is not an API for general use.
Why are you wanting to peek into the reference count of a module?
Shouldn't you have everything covered by properly recounting all your
data objects? (Preferably via the kref API.)
