env->test_state_freq flag can be set by user by passing BPF_F_TEST_STATE_FREQ program flag. This is used in a bunch of selftests to have predictable state checkpoints at every jump and so on. Currently, bounded loop handling heuristic ignores this flag if number of processed jumps and/or number of processed instructions is below some thresholds, which throws off that reliable state checkpointing. Honor this flag in all circumstances by disabling heuristic if env->test_state_freq is set.

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.
