The usage of lat_fs is: lat_fs [-s <file size>] [-n <max files per dir>] [-P <parallelism>] [-W <warmup>] [-N <repetitions>] [<dir>] , it is clear `dir` is the last parameter. While handling the `state.tmpdir`, current code is reading from the first parameter. If we pass command like, `lat_fs -P 1 /usr/tmp`, `tmpdir` will be `-P`, which is invalid path and tempnam() call falls back to /tmp, not the expected dir `/usr/tmp`.
