Enable the raw_spinlock vs. spinlock nesting checks which ensure
that the lock nesting rules for PREEMPT_RT enabled kernels are
not violated.
- NOTE: There are known nesting problems. So if you enable this

- addressed which is work in progress. This config switch allows to
- identify and analyze these problems. It will be removed and the
