[lttng-dev] [RELEASE] Userspace RCU 0.14.1 and 0.13.4

[Mathieu Desnoyers]

Hi,

This is a release announcement for the version 0.14.1 and 0.13.4
of the liburcu project.

Included in those releases are bug fixes, new architecture support,
OpenBSD support, and documentation updates.

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.
