[ Upstream commit 4793cb599b1bdc3d356f0374c2c99ffe890ae876 ]
The test case test_cgcore_lesser_ns_open only tasks effect when cgroup2
is mounted with "nsdelegate" mount option. If it misses this option, or
is remounted without "nsdelegate", the test case will fail. For example,
running bpf/test_cgroup_storage first, and then run cgroup/test_core will
fail on test_cgcore_lesser_ns_open. Skip it if "nsdelegate" is not
detected in cgroup2 mount options.

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.
