10 executing, and by how much, including both user-level and kernel code.
14 not 50, is to avoid lock-step sampling.
16 This is also an efficient profiler, as stack traces are frequency counted in
19 at the end of the profile, greatly reducing the kernel<->user transfer.
24 for an older version that may work on Linux 4.6 - 4.8.
