    I started updating my AIO tests to be a bit cleaner and added code
    to dirty some free blocks before the test. I also added options
    to set readsize, writesize, filesize and number of async i/o.
    I have update dio_sparse.c and aiodio_sparse.c, and I will be updating
    the rest tomorrow. The test also stops immediately if it see
    bad (non-zero) data by the readers.

    I've run dio_sparse and aiodio_sparse on test9 on ext3 on my 2-proc:

    $ dio_sparse
    non zero buffer at buf[0] => 0xaa,aa,aa,aa
    non-zero read at offset 69533696

    $ aiodio_sparse
    non zero buffer at buf[0] => 0xaa,aa,aa,aa
    non-zero read at offset 81854464

    With slab debug on, test9 still gets

    slab error in check_poison_obj(): cache `kiocb': object was modified after freeing

    I'll be testing test9-mm1 tomorrow and let you know what I see.

    Daniel
