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. Changelog: 2013-06-18 Userspace RCU 0.7.7 * rculfhash: document destroy context limitation * Fix: Use a filled signal mask to disable all signals * Document: rculfhash destroy and resize side-effect in 0.7 * Add "sparc" host cpu to configure.ac * Fix: tests/api.h use cpuset.h * Fix hurd-i386: move cpuset tests outside of sched_setaffinity conditional * Fix tests: finer-grained use of CPU_SET, CPU_ZERO and cpu_set_t * Test for CPU_SET * Fix build on architectures with HAVE_SCHED_GETCPU but without HAVE_SYSCONF * README: document that Clang 3.0 (based on LLVM 3.0) is supported * clang: silence "unused expression result" warning * rculfhash: add assertions on node alignment * uatomic: style fix Project website: http://lttng.org/urcu Download link: http://lttng.org/files/urcu/ -- Mathieu Desnoyers EfficiOS Inc. http://www.efficios.com
