Maintain a registry of registered struct_ops types in the per-btf (module) struct_ops_tab. This registry allows for easy lookup of struct_ops types that are registered by a specific module. It is a preparation work for supporting kernel module struct_ops in a latter patch. Each struct_ops will be registered under its own kernel module btf and will be stored in the newly added btf->struct_ops_tab. The bpf verifier and bpf syscall (e.g. prog and map cmd) can find the struct_ops and its btf type/size/id... information from btf->struct_ops_tab.

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.
