[ltt-dev] [RELEASE] Userspace RCU library (liburcu) 0.2.1

[Mathieu Desnoyers]

Hello,

Userspace RCU 0.2.1 includes:

- small header dependency fix for rculist.h.
- new "liburcu-bp.so" : "Bulletproof RCU", made especially for the UST
  userspace tracer. It's a library that sacrifices a bit of read-side
  performance for automatically monitoring thread creation/removal. See
  README for details.

Thanks,

Mathieu
