[PATCH v11 0/3]: perf: reduce data loss when profiling highly parallel CPU bound workloads

Currently in record mode the tool implements trace writing serially. The algorithm loops over mapped per-cpu data buffers and stores ready data chunks into a trace file using write() system call. At some circumstances the kernel may lack free space in a buffer because the other buffer's half
