Missed this originally - files is totally fine, for what it's worth, on Linux we could map this to hole punching too. So I don't think that's a show stopper at all, it'd be perfectly possible to define trim based workloads just on files. In fact, that's more flexible that what we currently support on Linux. -- Jens Axboe -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
