704 * Added urcu/cds.h and merged all "Concurrent Data Containers" (CDS)
705 into a single .so: liburcu-cds.so to have a single header/shared

707 support for RCU lists, queues and stacks at the moment.
708 * liburcu 0.6.0 now allows linking a single application with multiple
709 flavors of RCU. This required a library API change which is
710 incompatible with older 0.5.x liburcu. The .so version number

713 processes using fork() without following exec().

774 sys_membarrier() when available, and using liburcu-mb as a
