Good!  I'm currently doing the same in a backlevel kernel, as
contention for ha->hardware_lock can take up to 15% of our cpu time.
Having to duplicate the effort sucks, but getting regressions when
next upgrading the kernel would suck even more.  So I'm happy to see
the hardware lock become a plain hardware lock again. :)
