◆ process_buffer_size_limit

std::optional<uint64_t> lldb_private::TraceIntelPTStartRequest::process_buffer_size_limit

Required when doing "process tracing".

Limit in bytes on all the thread traces started by this "process trace" instance. When a thread is about to be traced and the limit would be hit, then a "tracing" stop event is triggered.
