... LWN.net FAQ . ... Read-copy-update (RCU) is a mutual exclusion technique which can operate without locking most of the time. It can yield significant performance benefits when the data to be protected is accessed via a pointer, is read frequently, changed rarely, and references to the structure are not held while a kernel thread sleeps. The core idea behind RCU is that, when the data requires updating, a pointer to a new structure containing the new data can be stored immediately. ...
