In Fedora34, libc-2.33.so has both .dynsym and .symtab sections and most of (not all) symbols moved to .dynsym. In this case, perf only decode the symbols in .symtab, and perf probe can not list up the functions in the library. To fix this issue, decode both .symtab and .dynsym sections.

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.
