Kernel Korner - Using RCU in the Linux 2.5 Kernel
RCU will become more important as CPU architecture continues to evolve. Nonetheless, other primitives always will be needed. It is quite likely that Rusty Russell's implementation of RCU (the call_rcu() and synchronize_kernel() primitives themselves) can be modified to be entirely free of locks, memory barriers and atomic instructions. This implementation might run faster than the current 2.5 kernel implementation.
Numerous people are looking at new uses of RCU in the VFS layer, VM code, filesystems and networking code. I look forward to continuing to learn about RCU and its uses and am grateful to the many people who have tried it out.
Paul E. McKenney has worked on SMP and NUMA algorithms for longer than he cares to admit. Prior to that, he worked on packet-radio and Internet protocols (but long before the Internet became popular). His hobbies include running and the usual house-wife-and-kids habit. This work represents the view of the author and does not necessarily represent the view of IBM.
