Userspace RCU 0.7.1

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 compile-fix release, fixing a compile issue introduced a few days before the 0.7.0 release. We plan to deploy a continuous integration test setup to catch this kind of issue earlier in a very near future.

Changelog:
2012-05-24 Userspace RCU 0.7.1
