The btf__get_from_id() function was deprecated in favour of btf__load_from_kernel_by_id(), but it is still avaiable, so use it to provide a weak function btf__load_from_kernel_by_id() for older libbpf when building perf with LIBBPF_DYNAMIC=1, i.e. using the system's libbpf package.

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.
