Summary

We are staring with this PR a new cycle to bring a new eBPF function for netdata, this time the focus is VFS that is also a function that consumes a lot of resources from host.

Test Plan

  1. Get binaries according your LIBC from this link and extract them inside a directory, for example: ../artifacts. You can also get everything for glibc [here](UPLOAD FILE WITH ALL BINARIES TO SIMPLIFY REVIEWERS).

  2. Extract them running:

    $ for i in `ls *.zip`; do unzip $i; rm .gitkeep ; rm $i; done
$ for i in `ls *.xz`; do tar -xf $i; rm $i* ; done

  3. Compile branch an run the following tests:

    # make clean; make tester
# for i in `seq 0 3`; do ./kernel/legacy_test --netdata-path ../artifacts --content --vfs --iteration 1 --pid $i --log-path file_pid$i.txt; done

  4. Every test should ends with Success, unless you do not have a specific target (function) available.
