The bpf events are created by the same macro magic as tracefs trace events are. But to hook into bpf, it has its own code. It duplicates many of the same macros as the tracefs macros and this is an issue because it misses bug fixes as well as any new enhancements that come with the other trace macros. As the trace macros have been put into their own staging files, have bpf take advantage of this and use the tracefs stage 6 macros that the "fast ssign" portion of the trace event macro uses.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
