It is found that disabling KASAN instrumentation when compiling
lockdep.c can significantly improve the performance of RT debug kernel
while the performance benefit of non-RT debug kernel is relatively
modest.

This series also include a patch to add locking events to the rtmutex
slow paths for better analysis of the different performance behavior
between RT and non-RT debug kernels.
