My two cents:

The simple method is to identify the change code belonging
to which subcomponent, e.g. mm, you can use the LTP/mm
to cover the Linux build.

In LTP runtest/ directory, there are many task file mapping Linux
kernel relates module, but it doesn't 100% precise, for example,
ltp/runtest/syscalls include kinds of syscall's tests, it is hard to say
which kernel subcomponents it covers, but fortunately, LTP supports
creating a customized taskfile, which means people can reorder
them in a new specified file to cover some kernel-module changes
they wanted.

These highly depend on how people do the testing triage work.
