Leon Hwang b83b936f3e selftests/bpf: Add testcases for tailcall hierarchy fixing
Add some test cases to confirm the tailcall hierarchy issue has been fixed.

On x64, the selftests result is:

cd tools/testing/selftests/bpf && ./test_progs -t tailcalls
327/18  tailcalls/tailcall_bpf2bpf_hierarchy_1:OK
327/19  tailcalls/tailcall_bpf2bpf_hierarchy_fentry:OK
327/20  tailcalls/tailcall_bpf2bpf_hierarchy_fexit:OK
327/21  tailcalls/tailcall_bpf2bpf_hierarchy_fentry_fexit:OK
327/22  tailcalls/tailcall_bpf2bpf_hierarchy_fentry_entry:OK
327/23  tailcalls/tailcall_bpf2bpf_hierarchy_2:OK
327/24  tailcalls/tailcall_bpf2bpf_hierarchy_3:OK
327     tailcalls:OK
Summary: 1/24 PASSED, 0 SKIPPED, 0 FAILED

On arm64, the selftests result is:

cd tools/testing/selftests/bpf && ./test_progs -t tailcalls
327/18  tailcalls/tailcall_bpf2bpf_hierarchy_1:OK
327/19  tailcalls/tailcall_bpf2bpf_hierarchy_fentry:OK

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 reStructuredText 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.
