[ Upstream commitda1055b673] The linked list failure test 'pop_front_off' and 'pop_back_off' currently rely on matching exact instruction and register values. The purpose of the test is to ensure the offset is correctly incremented for the returned pointers from list pop helpers, which can then be used with container_of to obtain the real object. Hence, somehow obtaining the information that the offset is 48 will work for us. Make the test more robust by relying on verifier error string of bpf_spin_lock and remove dependence on fragile instruction index or register number, which can be affected by different clang versions used to build the selftests.

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.
