I don't see why it would be better, there are no obvious advantages, but
some obvious disadvantages.
Here our principles start clashing. We can't do this for several
* The declaration is static, so it has to be surrounded by #if
defined(CONFIG_SMP) would waste all the places in the code. This is
controverse to our goal to make changes as local as possible.
If we don't, we end up with warnings in the code for almost every
* Since some of us started hating typedefs, we don't have anything to
declare anymore. You simply can not rely that a spinlock is
represented by struct spinlock on all possible systems.
So to get this done right, we would have to go back to spinlock_t,
in which case I would vote to also go back to device_t and all the
others, so we stay consistent.
