I read the following info from kernel selftest documentation
https://www.kernel.org/doc/html/latest/dev-tools/kselftest.html
"The kernel contains a set of “self tests” under the
tools/testing/selftests/ directory. These are intended to be small tests
to exercise individual code paths in the kernel. Tests are intended to
be run after building, installing and booting a kernel."
So, we can build older kernel(use older kernel source) if we want to
test older kernel.
IMO, kerenl selftest is different from other testsuit(ie ltp, this
shuould think about api changes because ltp may test on different kernel).
Also cc ltp co-maintainer Petr
Or, did I miss something?
