[lttng-dev] [RELEASE] Userspace RCU 0.11.3 and 0.12.2

[Mathieu Desnoyers]

Hi,

This is a bugfix release announcement for the Userspace RCU library
(liburcu) for its two currently maintained branches.

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.

The Changelog entries highlight the relevant fixes:
