Paul Moore 87aea4848d audit: don't WARN_ON_ONCE(!current->mm) in audit_exe_compare() commit `969d90ec21` upstream. eBPF can end up calling into the audit code from some odd places, and some of these places don't have @current set properly so we end up tripping the `WARN_ON_ONCE(!current->mm)` near the top of `audit_exe_compare()`. While the basic `!current->mm` check is good, the `WARN_ON_ONCE()` results in some scary console messages so let's drop that and just do the regular `!current->mm` check to avoid problems.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
