[ Upstream commit 61ca36c8c4eb3bae35a285b1ae18c514cde65439 ] !perfmon_capable() is checked before the last switch(func_id) in bpf_base_func_proto. Thus, the cases BPF_FUNC_trace_printk and BPF_FUNC_snprintf_btf can be moved to that last switch(func_id) to omit the inline !perfmon_capable() checks.

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.
