Hmm, the copy here is gratuitous.  Using current->comm is safe, just
possibly ambigious if someone is changing the task name at the same time.

And we really want this one line anyway:

                printk(KERN_WARNING
                       "%s: waiting module removal not supported: please 
upgrade\n",
                        current->comm);

BTW, did you actually hit this?

Thanks,
Rusty.
