Add a kselftest to cover bpf auto-detachment functionality. The test creates a cgroup, associates some resources with it, attaches a couple of bpf programs and deletes the cgroup. Then it checks that bpf programs are going away in 5 seconds. Expected output: $ ./test_cgroup_attach #override:PASS #multi:PASS #autodetach:PASS test_cgroup_attach:PASS On a kernel without auto-detaching: $ ./test_cgroup_attach #override:PASS #multi:PASS #autodetach:FAIL test_cgroup_attach:FAIL Signed-off-by: Roman Gushchin <guro@fb.com> Acked-by: Yonghong Song <yhs@fb.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org>
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.
