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

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

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

731 * library names changes: liburcu becomes the "default" version, using
732 sys_membarrier() when available, and using liburcu-mb as a
734 * The signal-based liburcu is renamed from liburcu to
735 liburcu-signal. People previously using the signal-based

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