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.

        * fix: uatomic_set return value compile fix for non-x86 arch.
