It also tracks 4 contention points per class. A contention point is a call site
that had to wait on lock acquisition.

- CONFIGURATION

Lock statistics are enabled via CONFIG_LOCK_STATS.

- USAGE

Enable collection of statistics:

# echo 1 >/proc/sys/kernel/lock_stat

Disable collection of statistics:

# echo 0 >/proc/sys/kernel/lock_stat

Look at the current lock statistics:
