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

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

769 * library names changes: liburcu becomes the "default" version, using
770 sys_membarrier() when available, and using liburcu-mb as a

797 * new "liburcu-bp.so" : "Bulletproof RCU", made especially for
798 the UST userspace tracer. It's a library that sacrifices a bit
