Yafang Shao says: ==================== The target_btf_id can help us understand which kernel function is linked by a tracing prog. The target_btf_id and target_obj_id have already been exposed to userspace, so we just need to show them. For some other link types like perf_event and kprobe_multi, it is not easy to find which functions are attached either. We may support ->fill_link_info for them in the future. v1->v2: - Skip showing them in the plain output for the old kernels. (Quentin) - Coding improvement.

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.
