[ltt-dev] [PATCH 0/3] Fixes for threads that are readers and writers, and lock-free queue example

[pbonzini@redhat.com (Paolo Bonzini)]

The first two patches are bugfixes meant for application.  They allow
using threads that are readers and writers with implementations other
than urcu-qsbr.  In addition, they allow early unregistering of
reader threads without risking deadlock with writers.

The third patch is a sample implementation of lock-free queue following
discussion with Paul last week.

They do not depend on the previous patch series.

Paolo Bonzini (3):
  add rcu_thread_{on,off}line to urcu-bp and urcu
  add rcu_thread_offline before rcu_unregister_thread
  lock-free queue with RCU-based garbage collection
