451 2011-06-10 Userspace RCU 0.6.0
452 * Added call_rcu() support, graciously contributed by Paul E. McKenney.
453 * Added urcu/cds.h and merged all "Concurrent Data Containers" (CDS)
454 into a single .so: liburcu-cds.so to have a single header/shared
455 object holding all concurrency-aware data containers. It provides
456 support for RCU lists, queues and stacks at the moment.
457 * liburcu 0.6.0 now allows linking a single application with multiple
458 flavors of RCU. This required a library API change which is
459 incompatible with older 0.5.x liburcu. The .so version number
460 is therefore bumped from 0 to 1 (e.g. liburcu.so.1).
461 * Added "atfork" handling API, documented in README. Only useful for
462 processes using fork() without following exec().
463 * Renaming the following files, keeping the old files (producing a
465 urcu/uatomic_arch.h -> urcu/uatomic.h
466 urcu/urcu-futex.h -> urcu/futex.h
467 urcu/urcu_ref.h -> urcu/ref.h
469 2011-03-04 Userspace RCU 0.5.4
470 * urcu-bp: Update fork() handling
474 extern void rcu_bp_before_fork(void);
475 extern void rcu_bp_after_fork_parent(void);
476 extern void rcu_bp_after_fork_child(void);
478 to handle fork gracefully. These disable signals and hold
479 the registry mutex across forks. (this flavor of the liburcu
480 library ("bp" for "bulletproof") is mainly used by UST, the
483 2011-03-03 Userspace RCU 0.5.3
484 * Add support for older ARM single-CPU architecturess (pre-ARMv7)
485 (thanks to Jason Wessel from WindRiver).
486 * Fix ARMv7 cmm_rmb/cmm_wmb primitives (use a dmb barrier).
487 * Remove leftover list_t type from urcu/list.h (namespace cleanup).
488 * urcu_defer: handle malloc error value.
489 * Update README file to describe urcu interaction with fork() when not
491 by an exec() system call.
493 2010-11-18 Userspace RCU 0.5.2
494 * Fix renaming error introduced in 0.5.0.
496 2010-11-18 Userspace RCU 0.5.1
497 * Fix renaming error introduced in 0.5.0. (incomplete fix)
499 2010-11-18 Userspace RCU 0.5.0
500 * Version 0.5.0 changes the API presented by memory model,
501 architecture abstraction and data structure primitives in
502 headers. The prefixes are, respectively:
503 - cmm_ : Concurrent Memory Model
504 - caa_ : Concurrent Architecture Abstraction
505 - cds_ : Concurrent Data Structures
507 2010-03-04 Userspace RCU 0.4.2
508 * Add generic uatomic ops support.
509 * Bugfix in urcu-bp. (rare garbage collection bug occurring in
510 multithreaded environment). Only affects urcu-bp users (UST).
512 2010-02-12 Userspace RCU 0.4.1
513 * s390: compilation fix.
515 2010-01-30 Userspace RCU 0.4.0
516 * API change: SIGURCU -> SIGRCU
517 * API changes: standardize on rcu_ prefix.
518 * API change: urcu_init -> rcu_init.
519 * urcu/config.h options renamed to CONFIG_RCU_HAVE_FENCE,
520 CONFIG_RCU_HAVE_FUTEX, CONFIG_RCU_SMP, CONFIG_RCU_COMPAT_ARCH.
521 ((moving from URCU -> RCU).
522 * library names changes: liburcu becomes the "default" version, using
523 sys_membarrier() when available, and using liburcu-mb as a
525 * The signal-based liburcu is renamed from liburcu to
526 liburcu-signal. People previously using the signal-based
527 "liburcu" will automatically be moved to the "default" liburcu
530 2009-11-16 Userspace RCU 0.3.1
531 * Add support for sparcv9 32-bit build.
532 * Update build system to use --host instead of --target.
534 2009-11-03 Userspace RCU 0.3.0
535 * API change for the "deferred work" interface.
537 2009-10-14 Userspace RCU 0.2.3
539 * Automated architecture detection, with i386 fallback.
540 * Detect if NR_futex is on the system, fallback on portable
542 * Add configure mode for UP-only systems.
544 2009-10-02 Userspace RCU 0.2.2
545 * Phases out rcu_publish_content() api.
546 * Adds type checking to urcu-pointer.h pointer exchange primitives.
548 2009-10-02 Userspace RCU 0.2.1
549 * small header dependency fix for rculist.h.
550 * new "liburcu-bp.so" : "Bulletproof RCU", made especially for
551 the UST userspace tracer. It's a library that sacrifices a bit
552 of read-side performance for automatically monitoring thread
553 creation/removal. See README for details.
555 2009-10-01 Userspace RCU 0.2
556 * Clarify usage of rcu_cmpxchg_pointer, rcu_xchg_pointer,
