I guess KVM hosts nowadays should have more than 2 threads (these tests are for bare metal), thus we don't have to note this also in the code, right? Anyway LGTM. Reviewed-by: Petr Vorel Waiting some time if Cyril, or somebody else will have time to look into this change before merging whole patchset. NOTE: whoever will merge this, it requires to change second commit: https://lore.kernel.org/ltp/20230526142745.GA813136@pevik/ Kind regards, Petr -- Mailing list info: https://lists.linux.it/listinfo/ltp
