Yes, exactly, tst_brk() is way too aggressive. tst_res(TINFO) is good enough to give the information without deliberately break all the tests. > LTP has been historically used for many different purposes, e.g. for > testing BSD compatibility layout for running Linux binaries and I fear > that hard stop on older kernel versions would break these usecases. +1.
