rcu: Document alternative RCU/reference-count algorithms

2012-11-08T19:44:38+00:00

The approach for mixing RCU and reference counting listed in the RCU documentation only describes one possible approach. This approach can result in failure on the read side, which is nice if you want fresh data, but not so good if you want simple code. This commit therefore adds two additional approaches that feature unconditional reference-count acquisition by RCU readers. These approaches are very similar to that used in the security code.
