McKenney" , Lai Jiangshan , Stephen Hemminger , Alan Stern List-Id: lttng-dev@lists.lttng.org Hi, 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 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. Those are bugfix releases for stable-0.7 and stable-0.8 branches. Small fixes to the tests (volatile in assert() and out of tree test fix) were not backported to stable-0.7 due to important changes to the test tree layout between 0.7 and 0.8.
