Thanks a lot for testing!
Pushed (with your Tested-by on my commit).

I did few cleanup changes in my commit (TINFO messages, fix missing local pid, redirect
stderr for wait to make it quiet, move TPASS message into run_stress()).

I wonder how to suppress kill message for the first cgroup pid:
/opt/ltp/testcases/bin/memcg_stress_test.sh: line 65: 14750 User defined signal 1   memcg_process_stress $mem_size $interval

This pid is the only one killed by -USR1, but line 65 is not in fist kill loop.
Therefore it cannot be killed by -KILL (second kill loop).

Kind regards,
Petr
