[RELEASE] Userspace RCU 0.5.0

[RELEASE] Userspace RCU 0.5.0

[Mathieu Desnoyers]

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:

* Version 0.5.0 changes the API presented by memory model, architecture
  abstraction and data structure primitives in headers. The prefixes are,
  respectively:
  - cmm_ : Concurrent Memory Model
  - caa_ : Concurrent Architecture Abstraction
  - cds_ : Concurrent Data Structures

This will make UST's life easier for instrumentation of large projects like
MariaDB and qemu.

[RELEASE] Userspace RCU 0.5.1

[Mathieu Desnoyers]

Well well, a renaming error seems to have crept into 0.5.0, which caused
problems with atomic operations on 64-bit architectures.

I made sure no other similar problem exist. Anyone using 0.5.0 (released a few
hours ago) should upgrade to 0.5.1.

Thank you,

Mathieu

Re: [RELEASE] Userspace RCU 0.5.2

s/0.5.1/0.5.2/g

Now works fine on non-x86 architectures. I'll have to be more cautious in the
future for such large changes.
