Great idea, but I wouldn't tst_brk() on older kernels, I would just print a message that there may be failures becuase older kernels are not supported or tested. 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. -- Cyril Hrubis chrubis@suse.cz -- Mailing list info: https://lists.linux.it/listinfo/ltp
