//
// Read-Copy-Update (RCU).
//
// RCU synchronization allows concurrent access to shared data structures,
// such as linked lists, trees, or hash tables, without using traditional locking methods
// in scenarios where read operations are frequent and need to be fast.
// It is particularly useful in multi-threaded environments where multiple threads
// may read from the same data structure while one or more threads may modify it.
// @remarks RCU synchronization is not for general-purpose synchronization.
// Teb->Rcu is used to store the RCU state.
