McKenney" , Lai Jiangshan , Stephen Hemminger , Alan Stern List-Id: lttng-dev@lists.lttng.org liburcu is a LGPLv2.1 userspace RCU (read-copy-update) library. This data synchronization library provides read-side access which scales linearly with the number of cores. It does so by allowing multiples 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. This is a bugfix release. Changelog: 2014-10-21 Userspace RCU 0.8.5 * Fix: preserve example files' timestamps when copying * rculfhash: remove duplicated code * rculfhash: handle pthread_create failures * rculfhash: fall back to single-threaded resize on calloc failure * x86: drop extra semi-colon in caa_cpu_relax * Fix: Use after free in rcu_barrier() * Fix: rcu_barrier(): uninitialized futex field * call_rcu threads should clear their PAUSED flag when they unpause * Fix: bring back dummy rcu_bp_exit symbol Project website: http://urcu.so Git repository: git://git.urcu.so/urcu.git -- Mathieu Desnoyers EfficiOS Inc. http://www.efficios.com
