[ltt-dev] Userspace RCU library, now with autotools

[Mathieu Desnoyers]

Hello,

Pierre-Marc contributed patches moving urcu to autotools. I would
appreciate if someone can test it on powerpc and s390 before I can
proceed to a release.

Available at:

git://lttng.org/userspace-rcu.git

See updated README for details.

Thanks,

Mathieu
