Micah Morton 92c005a117 LSM: SafeSetID: fix userns bug in selftest
Not sure how this bug got in here but its been there since the original
merge. I think I tested the code on a system that wouldn't let me
clone() with CLONE_NEWUSER flag set so had to comment out these
test_userns invocations.

Trying to map UID 0 inside the userns to UID 0 outside will never work,
even with CAP_SETUID. The code is supposed to test whether we can map
UID 0 in the userns to the UID of the parent process (the one with
CAP_SETUID that is writing the /proc/[pid]/uid_map file).

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.
