[PATCH RFC 0/4] Add support for synchronous signals on perf events

2021-02-23 Thread Marco Elver
The perf subsystem today unifies various tracing and monitoring features, from both software and hardware. One benefit of the perf subsystem is automatically inheriting events to child tasks, which enables process-wide events monitoring with low overheads. By default perf events are non-intrusive,
