Message

Petr Pavlu Dec. 5, 2023, 4:17 p.m. UTC

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.

Petr Pavlu (3):
  tracing: Fix incomplete locking when disabling buffered events
  tracing: Fix a warning when allocating buffered events fails
  tracing: Fix a possible race when disabling buffered events
