This group contains the SMP lock implementation.
The SMP lock provides mutual exclusion in SMP systems at the lowest level.
The SMP lock is implemented as a ticket lock. This provides fairness in case of concurrent lock attempts.
This SMP lock API uses a local context for acquire and release pairs. Such a context may be used to implement for example the Mellor-Crummey and Scott (MCS) locks in the future.
