Linux kernel source tree
7b99f75942
v1.25 of pahole supports filtering out functions with multiple inconsistent function prototypes or optimized-out parameters from the BTF representation. These present problems because there is no additional info in BTF saying which inconsistent prototype matches which function instance to help guide attachment, and functions with optimized-out parameters can lead to incorrect assumptions about register contents. So for now, filter out such functions while adding BTF representations for functions that have "."-suffixes (foo.isra.0) but not optimized-out parameters. This patch assumes that below linked changes land in pahole for v1.25. Issues with pahole filtering being too aggressive in removing functions appear to be resolved now, but CI and further testing will confirm.

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.
