[libvirt] [PATCH 0/2] Last debug buffer patches: locking and docs

That's the remaining changes left for the debug buffer. The first patch is the one removing locking in the signal error handler. As discussed it's better to have a risk of slightly corrupted output in the log dump than have a risk crashing due to the unsafe locking operations in the signal handler. The second patch documents the debug buffer changes and improve the logging page to add more structure, and more examples. Daniel
