Can you resend the remaining ones after fixing up this issue? I'll do that shortly. Some architectures don't select SRCU which I was not aware of and Paul is telling me that the "tiny kernel" people don't want it to be selected too much, so I've changed the code to fall back to using an rwsem for the synchronization if SRCU is not available.
