If private stack is used by any subprog, set that subprog prog->aux->jits_use_priv_stack to be true so later jit can allocate private stack for that subprog properly. Also set env->prog->aux->jits_use_priv_stack to be true if any subprog uses private stack. This is a use case for a single main prog (no subprogs) to use private stack, and also a use case for later struct-ops progs where env->prog->aux->jits_use_priv_stack will enable recursion check if any subprog uses private stack.

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 reStructuredText 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.
