It is the old maybe-preemptive way which is a mess. There is so much the kernel developer have to think off wrt. locking. Too many kind of contexts, per cpu variables, miriads of locking types. When I started to look at it I thought: What a mess. PREEMPT_RT basicly boils it down to: everything are threads, the only way to protect data is to use a mutex or use RCU. In short: Linux with PREEMPT_RT is much easier to understand and develop than with !PREEMPT_RT.
