I haven't actually seen the reports.

That said, I do think this should be improving. The random
architecture-specific code is largely going away, and we'll have a
unified rwsem.

It might obviously cause some pain initially, but I think long-term we
should be much better off, at least avoiding the "on particular
configurations" issue..
