Paul, if that's the only change needed, then I'll be happy to support it in
the unionfs2 series for 2.6.21 and any other kernel for which this is
needed.  All I need to do is for you to tell me which CONFIG_* option I
should use:

#ifdef CONFIG_rt_something
       struct compat_rw_semaphore rwsem;
#else
       struct rw_semaphore rwsem;
#endif

Also, can you tell me which kernel major 2.6.x versions the RT patches are
available for?

Thanks,
Erez.
