[PATCH v2 0/3] tracing: Simplify and fix "buffered event" synchronization

Posted by Petr Pavlu 2 years ago

Fix a few problems related to the maintenance of buffered events.

Changes since v1 [1]:
* Address found problems individually. The approach in v1 tried to
  simplify the buffered event synchronization but had performance
  issues.
