Please do.
I agree, this is the best way out of this mess. Furthermore, it would
also be nice to consolidate opt spinning in a common CONFIG option --
right now mutexes and rwsems create their own dependencies.
I would suggest adding a RWSEM_SPIN_ON_OWNER to control opt spinning in
rwsem. Currently MUTEX_SPIN_ON_OWNER is doing that for mutex, and it is
disabled when mutex debugging is turned on. So I think it is better to
allow them to be disabled separately.
