The tracepoint can't be used in code section where we are in the
middle of a state transition.
For example if we place a tracepoint inside start/stop_critical_section(),
lockdep complains with

The tracepoint can't be used in code section where we are in the
middle of a state transition.
For example if we place a tracepoint inside start/stop_critical_section(),
lockdep complains with
[0.035589] WARNING: CPU: 0 PID: 3 at kernel/locking/lockdep.c:3560 \
