Implement a trivial iterator returning same specified integer value N times as part of bpf_testmod kernel module. Add selftests to validate everything works end to end. We also reuse these tests as "verification-only" tests to validate that kernel prints the state of custom kernel module-defined iterator correctly: fp-16=iter_testmod_seq(ref_id=1,state=drained,depth=0) "testmod_seq" part is an iterator type, and is coming from module's BTF data dynamically at runtime.

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.
