605 * Add missing headers into release tarball:
606 urcu-call-rcu-impl.h and urcu-defer-impl.h
608 2011-06-10 Userspace RCU 0.6.0
609 * Added call_rcu() support, graciously contributed by Paul E. McKenney.
610 * Added urcu/cds.h and merged all "Concurrent Data Containers" (CDS)
611 into a single .so: liburcu-cds.so to have a single header/shared
612 object holding all concurrency-aware data containers. It provides
613 support for RCU lists, queues and stacks at the moment.
614 * liburcu 0.6.0 now allows linking a single application with multiple
615 flavors of RCU. This required a library API change which is
616 incompatible with older 0.5.x liburcu. The .so version number
617 is therefore bumped from 0 to 1 (e.g. liburcu.so.1).
618 * Added "atfork" handling API, documented in README. Only useful for
619 processes using fork() without following exec().
620 * Renaming the following files, keeping the old files (producing a
622 urcu/uatomic_arch.h -> urcu/uatomic.h
623 urcu/urcu-futex.h -> urcu/futex.h
624 urcu/urcu_ref.h -> urcu/ref.h

636 the registry mutex across forks. (this flavor of the liburcu
637 library ("bp" for "bulletproof") is mainly used by UST, the

657 * Version 0.5.0 changes the API presented by memory model,
658 architecture abstraction and data structure primitives in

660 - cmm_ : Concurrent Memory Model
661 - caa_ : Concurrent Architecture Abstraction
662 - cds_ : Concurrent Data Structures
664 2010-03-04 Userspace RCU 0.4.2

677 CONFIG_RCU_HAVE_FUTEX, CONFIG_RCU_SMP, CONFIG_RCU_COMPAT_ARCH.
678 ((moving from URCU -> RCU).
679 * library names changes: liburcu becomes the "default" version, using
680 sys_membarrier() when available, and using liburcu-mb as a
682 * The signal-based liburcu is renamed from liburcu to
683 liburcu-signal. People previously using the signal-based
684 "liburcu" will automatically be moved to the "default" liburcu

706 * small header dependency fix for rculist.h.
707 * new "liburcu-bp.so" : "Bulletproof RCU", made especially for
708 the UST userspace tracer. It's a library that sacrifices a bit
709 of read-side performance for automatically monitoring thread
710 creation/removal. See README for details.
