694 * Added urcu/cds.h and merged all "Concurrent Data Containers" (CDS)
695 into a single .so: liburcu-cds.so to have a single header/shared
696 object holding all concurrency-aware data containers. It provides
697 support for RCU lists, queues and stacks at the moment.
698 * liburcu 0.6.0 now allows linking a single application with multiple
699 flavors of RCU. This required a library API change which is
700 incompatible with older 0.5.x liburcu. The .so version number

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

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