Hi,

Even though the urcu stable-0.7 branch was supposed to be end
of life, there is one last important fix for the urcu-signal flavor
that was sitting in that branch that I would like to release
before taking it away for good. All the good zombie movies start
like this, right ?

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.

Changelog:
2016-04-26 Userspace RCU 0.7.17
        * Fix: urcu-signal: smp_mb_master() needs registry lock
