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.
Changelog:
- Added call_rcu() support, graciously contributed by Paul E. McKenney.
- Added urcu/cds.h and merged all "Concurrent Data Containers" (CDS)
into a single .so: liburcu-cds.so to have a single header/shared
object holding all concurrency-aware data containers. It provides
support for RCU lists, queues and stacks at the moment.
- liburcu 0.6.0 now allows linking a single application with multiple
flavors of RCU. This required a library API change which is
incompatible with older 0.5.x liburcu. The .so version number
is therefore bumped from 0 to 1 (e.g. liburcu.so.1).
- Added "atfork" handling API, documented in README. Only useful for
processes using fork() without following exec().
- Renaming the following files, keeping the old files (producing a
compiler warning):
urcu/uatomic_arch.h -> urcu/uatomic.h
urcu/urcu-futex.h -> urcu/futex.h
urcu/urcu_ref.h -> urcu/ref.h

I get the same thing from the tarball. But the git tree works just fine,
so my guess is that the tarball creation left out a couple of files.
Thanx, Paul

Indeed, I missed those two headers in the Makefile.am EXTRA_DIST. I just
released 0.6.1, which fixes this issue. I've made sure the tarball
builds fine.
Thanks for reporting this so quickly!
