# These tests will only run correctly if the kernel and libaio has been compiled
# with at least a 3.3.X GCC. Older versions of the compiler will seg fault.

[-e 1] [-x 1] [-j 1] [-t 1]
        -o = optional partition allows some of the tests to utilize multiple filesystems to further stress AIO/DIO
        -e = test ex2 filesystem.
        -t = test ext3 filesystem
        -j = test JFS filesystem
        -x = test XFS filesystem
                    or
        -a = test all supported filesystems, this will override any other filesystem flags passed.

        - a 1 turns on the test for the above supported filesystem, just omit passing the flag to skip that filesystem.

        - A Large file should be passed to fully stress the test. You must pass at least one filesystem to test, you can pass any combination
          but there is not a default filesystem. ReiserFS does not support AIO so these tests will not support ReiserFS.

        - WARNING !! The partition you pass will be overwritten. This is a destructive test so only pass a partition where data can be destroyed.
