But, it's not a snooze lock, it's a spin lock! A snooze lock would imply that a process goes to sleep and yields the processor. A spin lock does not yield, it's in fact the opposite of a "sleep" lock.
If I understand the naming dilemma, the problem is that the old spin_locks which will not be renamed are in fact becoming sleep locks. If your naming convention is adopted, you would have spin_locks which sleep, and snooze_locks which spin!
So, raw_spinlock or real_spinlock seem more appropriate to me.
