Currently the bpf selftests are skipped by default, so is someone would
like to run the tests one would need to run:
$ make TARGETS=bpf SKIP_TARGETS="" kselftest
To overwrite the SKIP_TARGETS that defines bpf by default. Also,
following the BPF instructions[1], to run the bpf selftests one would
need to enter in the tools/testing/selftests/bpf/ directory, and then
run make, which is not the standard way to run selftests per it's
documentation.
For the reasons above stop mentioning bpf in the kselftests as examples
of how to run a test suite.

The default timeout for selftests tests is 45 seconds. Although
we already have 13 settings for tests of about 96 sefltests which
use a timeout greater than this, we want to try to avoid encouraging
more tests to forcing a higher test timeout as selftests strives to
run all tests quickly. Selftests also uses the timeout as a non-fatal
error. Only tests runners which have control over a system would know
if to treat a timeout as fatal or not.
To help with all this:
o Enhance documentation to avoid future increases of insane timeouts
o Add the option to allow overriding the default timeout with test
runners with a command line option

Make any kselftest test module (using the kselftest_module framework)
taint the kernel with TAINT_TEST on module load.
Also mark the module as a test module using MODULE_INFO(test, "Y") so
that other tools can tell this is a test module. We can't rely solely
on this, though, as these test modules are also often built-in.
Finally, update the kselftest documentation to mention that the kernel
should be tainted, and how to do so manually (as below).
Note that several selftests use kernel modules which are not based on
the kselftest_module framework, and so will not automatically taint the
kernel.
This can be done in two ways:
- Moving the module to the tools/testing directory. All modules under
this directory will taint the kernel.
- Adding the 'test' module property with:
MODULE_INFO(test, "Y")
Similarly, selftests which do not load modules into the kernel generally
should not taint the kernel (or possibly should only do so on failure),
as it's assumed that testing from user-space should be safe. Regardless,
they can write to /proc/sys/kernel/tainted if required.

pass along any variables to `make install` to influence what should be
built. This can result in an early error on the command line ("Unknown
tarball format TARGETS=XXX"), or unexpected test failures as the
tarball contains tests people wanted to skip on purpose.
Since the makefile already contains all the logic, we can add a target
for packaging. Keep the default .gz target the script uses, and actually
extend the supported formats by using tar's autodetection.
To not break current workflows, keep the gen_kselftest_tar.sh script as
it is, with an added suggestion to use the makefile target instead.

kselftest runs as a userspace process. Sometimes we need to test things
from kernel space. One way of doing this is by creating a test module.
Currently doing so requires developers to write a bunch of boiler plate
in the module if kselftest is to be used to run the tests. This means
we currently have a load of duplicate code to achieve these ends. If we
have a uniform method for implementing test modules then we can reduce
code duplication, ensure uniformity in the test framework, ease code
maintenance, and reduce the work required to create tests. This all
helps to encourage developers to write and run tests.
Add a C header file that can be included in test modules. This provides
a single point for common test functions/macros. Implement a few macros
that make up the start of the test framework.
Add documentation for new kselftest header to kselftest documentation.
