Eduard Zingerman f8acfdd044 selftests/bpf: BPF test_verifier selftests for bpf_loop inlining
A number of test cases for BPF selftests test_verifier to check how
bpf_loop inline transformation rewrites the BPF program. The following
cases are covered:
 - happy path
 - no-rewrite when flags is non-zero
 - no-rewrite when callback is non-constant
 - subprogno in insn_aux is updated correctly when dead sub-programs
   are removed
 - check that correct stack offsets are assigned for spilling of R6-R8
   registers

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.
