Subject: [PATCH v2 0/3] tracing: Simplify and fix "buffered event" synchronization
Date: Tue, 5 Dec 2023 17:17:33 +0100 [thread overview]
Message-ID: <20231205161736.19663-1-petr.pavlu@suse.com> (raw)
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.
