600 * Add missing headers into release tarball:
601 urcu-call-rcu-impl.h and urcu-defer-impl.h
603 2011-06-10 Userspace RCU 0.6.0
604 * Added call_rcu() support, graciously contributed by Paul E. McKenney.
605 * Added urcu/cds.h and merged all "Concurrent Data Containers" (CDS)
606 into a single .so: liburcu-cds.so to have a single header/shared
607 object holding all concurrency-aware data containers. It provides
608 support for RCU lists, queues and stacks at the moment.
609 * liburcu 0.6.0 now allows linking a single application with multiple
610 flavors of RCU. This required a library API change which is
611 incompatible with older 0.5.x liburcu. The .so version number
612 is therefore bumped from 0 to 1 (e.g. liburcu.so.1).
613 * Added "atfork" handling API, documented in README. Only useful for
614 processes using fork() without following exec().
615 * Renaming the following files, keeping the old files (producing a
617 urcu/uatomic_arch.h -> urcu/uatomic.h
618 urcu/urcu-futex.h -> urcu/futex.h
619 urcu/urcu_ref.h -> urcu/ref.h

630 to handle fork gracefully. These disable signals and hold
631 the registry mutex across forks. (this flavor of the liburcu
632 library ("bp" for "bulletproof") is mainly used by UST, the

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

655 - cmm_ : Concurrent Memory Model
656 - caa_ : Concurrent Architecture Abstraction
657 - cds_ : Concurrent Data Structures
659 2010-03-04 Userspace RCU 0.4.2

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

700 2009-10-02 Userspace RCU 0.2.1
701 * small header dependency fix for rculist.h.
702 * new "liburcu-bp.so" : "Bulletproof RCU", made especially for
703 the UST userspace tracer. It's a library that sacrifices a bit
704 of read-side performance for automatically monitoring thread
705 creation/removal. See README for details.
