List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 22 Jul 2011 21:23:43 -0000 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. Changelog: * uatomic: Fix ARM build errors in uatomic. * urcu tests: hold mutex across use of custom allocator. * Portability fixes to support FreeBSD 8.2.
