This data synchronization library provides read-side access which scales linearly with the number of cores. It does so by allowing multiple copies of a given data structure to live at the same time, and by monitoring the data structure accesses to detect grace periods after which memory reclamation is possible. liburcu-cds provides efficient data structures based on RCU and lock-free algorithms. Those structures include hash tables, queues, stacks, and doubly-linked lists. Changelog: 2016-04-26 Userspace RCU 0.8.9 * Fix: handle reference count overflow * Fix: compat_futex should work-around futex signal-restart kernel bug * Fix: urcu-signal: smp_mb_master() needs registry lock * Fix: rculfhash only needs to include urcu-pointers.h * Fix: format string signedness * Use gcc atomics on aarch64/powerpc64le * Fix: compat_futex: uninitialized ret variable * Fix: compat_futex_noasync: don't override return value * Fix: stable-0.8 branch does not have syscall-compat.h * Fix: dynamic fallback to compat futex on sys_futex ENOSYS Project website: http://liburcu.org Git repository: git://git.liburcu.org/urcu.git -- Mathieu Desnoyers EfficiOS Inc. http://www.efficios.com
