I tried building against the full source tree from the kernel srpm. This 
works before a "make modules" in this tree has created the Module.symvers 
file. Afterwards it does not anymore, the error being exactly the one 
I posted yesterday.

Removing this file from the tree from the kernel-devel RPM has the same 
effect: building an unpatched openafs-1.4.2 against this tree now works.

I guess there is no Module.symvers in your kernel tree? And hence no 
build problems with GPL-only symbols? And no modversions either, but
that's no problem since you build specifically for each kernel?

But isn't loading such a module supposed to fail? Is it only in this 
special case that it doesn't, because of the "weak" definition of 
tasklist_lock in the AFS module and/or because of the fallback to 
rcu_read_lock?
