> We can just operate on the wq_tail directly (in the process descriptor).
> This allows us to remove the duplicated tail from the client. While I'm
> here let's also remove the constants kept in the client and document our
> locking requirements. This causes a small change in one of GuC debugfs
> files. We're no longer reporting constant values (which I don't think
> is a problem), but we're also no longer reporting the tail (does anyone
> care?).
