  1. bpftrace: add version 0.20.3, and associated tools 

    Rationale, maybe useful for finding performance issues with our
storage. Bcc and bpftrace (what sits on top of bcc) make use of
extended BPF (Berkeley Packet Filters),

Treat this as experimental, since some features require kernel
options we do not use - so YMMV :)

To start you must be root and also need to make the kernelheaders
of the running kernel available via sysfs.

  #> insmod kheaders

  -> /sys/kernel/kheaders.tar.xz

More info:

 https://github.com/bpftrace/bpftrace

P.S. Sometimes the actual headers are also found under
/lib/modules/*/build/include/linux .
