This patch adds a btf_dedup test exercising logic of STRUCT<->FWD resolution and validating that STRUCT is not resolved to a FWD. It also forces hash collisions, forcing both FWD and STRUCT to be candidates for each other. Previously this condition caused infinite loop due to FWD pointing to STRUCT and STRUCT pointing to its FWD.

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.
