Teach libbpf to search for candidate types for CO-RE relocations across kernel modules BTFs, in addition to vmlinux BTF. If at least one candidate type is found in vmlinux BTF, kernel module BTFs are not iterated. If vmlinux BTF has no matching candidates, then find all kernel module BTFs and search for all matching candidates across all of them. Kernel's support for module BTFs are inferred from the support for BTF name pointer in BPF UAPI.

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.
