The resolve_btfids tool scans elf object for .BTF_ids section and resolves its symbols with BTF ID values. It will be used to during linking time to resolve arrays of BTF ID values used in verifier, so these IDs do not need to be resolved in runtime. The expected layout of .BTF_ids section is described in main.c header. Related kernel changes are coming in following changes. Build issue reported by 0-DAY CI Kernel Test Service.

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.
