Here it is! This conversion loses the "selftest=..." argument to modprobe.

And I think all of these files could be reduced to a single script
that did something like:

. $path/kselftest_module.sh

run "strscpy" test_strscpy
run "bitmap" test_bitmap
run "prime numbers" prime_numbers selftest=65536

and kselftest_module.sh could define a "trap {...} EXIT" to perform
the reporting of everything that got run.
