558 2011-06-13 Userspace RCU 0.6.2
559 * Fix build on powerpc.
561 2011-06-13 Userspace RCU 0.6.1
562 * Add missing headers into release tarball:
563 urcu-call-rcu-impl.h and urcu-defer-impl.h
565 2011-06-10 Userspace RCU 0.6.0
566 * Added call_rcu() support, graciously contributed by Paul E. McKenney.
567 * Added urcu/cds.h and merged all "Concurrent Data Containers" (CDS)
568 into a single .so: liburcu-cds.so to have a single header/shared
569 object holding all concurrency-aware data containers. It provides
570 support for RCU lists, queues and stacks at the moment.
571 * liburcu 0.6.0 now allows linking a single application with multiple
572 flavors of RCU. This required a library API change which is
573 incompatible with older 0.5.x liburcu. The .so version number
574 is therefore bumped from 0 to 1 (e.g. liburcu.so.1).
575 * Added "atfork" handling API, documented in README. Only useful for
576 processes using fork() without following exec().
577 * Renaming the following files, keeping the old files (producing a
579 urcu/uatomic_arch.h -> urcu/uatomic.h
580 urcu/urcu-futex.h -> urcu/futex.h
581 urcu/urcu_ref.h -> urcu/ref.h

592 to handle fork gracefully. These disable signals and hold
593 the registry mutex across forks. (this flavor of the liburcu
594 library ("bp" for "bulletproof") is mainly used by UST, the
597 2011-03-03 Userspace RCU 0.5.3
598 * Add support for older ARM single-CPU architecturess (pre-ARMv7)
599 (thanks to Jason Wessel from WindRiver).

601 * Remove leftover list_t type from urcu/list.h (namespace cleanup).
602 * urcu_defer: handle malloc error value.
603 * Update README file to describe urcu interaction with fork() when not
605 by an exec() system call.

613 2010-11-18 Userspace RCU 0.5.0
614 * Version 0.5.0 changes the API presented by memory model,
615 architecture abstraction and data structure primitives in
616 headers. The prefixes are, respectively:
617 - cmm_ : Concurrent Memory Model
618 - caa_ : Concurrent Architecture Abstraction
619 - cds_ : Concurrent Data Structures
621 2010-03-04 Userspace RCU 0.4.2
622 * Add generic uatomic ops support.
623 * Bugfix in urcu-bp. (rare garbage collection bug occurring in

627 * s390: compilation fix.
629 2010-01-30 Userspace RCU 0.4.0
630 * API change: SIGURCU -> SIGRCU
631 * API changes: standardize on rcu_ prefix.
632 * API change: urcu_init -> rcu_init.
633 * urcu/config.h options renamed to CONFIG_RCU_HAVE_FENCE,
634 CONFIG_RCU_HAVE_FUTEX, CONFIG_RCU_SMP, CONFIG_RCU_COMPAT_ARCH.
635 ((moving from URCU -> RCU).
636 * library names changes: liburcu becomes the "default" version, using
637 sys_membarrier() when available, and using liburcu-mb as a
639 * The signal-based liburcu is renamed from liburcu to
640 liburcu-signal. People previously using the signal-based
641 "liburcu" will automatically be moved to the "default" liburcu

662 2009-10-02 Userspace RCU 0.2.1
663 * small header dependency fix for rculist.h.
664 * new "liburcu-bp.so" : "Bulletproof RCU", made especially for
665 the UST userspace tracer. It's a library that sacrifices a bit
666 of read-side performance for automatically monitoring thread
667 creation/removal. See README for details.
669 2009-10-01 Userspace RCU 0.2
670 * Clarify usage of rcu_cmpxchg_pointer, rcu_xchg_pointer,
