Thanks for sending this.

Note, once the libtracefs settles down, I plan on committing the files
that are generated by bison and flex, so it shouldn't be a requirement
once libtracefs 1.3 is officially released. That is, because the files
generated by flex and bison will be included in the repository, you do
not need to include bison or flex to build it. Unless you plan on
modifying the bison and flex source files.

Also, can we have a Fedora version? If you don't know what that is, I
could come up with the equivalents.
