The refactoring of SYSCALL_DEFINE0() macros removed the ABI stubs and simply defines __abi_sys_$NAME as alias of __do_sys_$NAME. As a result kallsyms_lookup() returns "__do_sys_$NAME" which does not match with the declared trace event name. See also commit1c758a2202("tracing/x86: Update syscall trace events to handle new prefixed syscall func names"). Add __do_sys_ to the valid prefixes which are checked in arch_syscall_match_sym_name().

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.
