    SubjectBadness in as_completed_request warning

    I'm getting a "badness" warning from as_iosched.c, line 917.
    This is on 2.6.0-test4-mm6, running on a 2 cpu x86.

    The warning occurs when I run three or more instances of mkfs.ext2, where
    each mkfs is running on its own disk. If I run four or more mkfs's
    on paritions all on the same disk I don't get this warning.
    The more instances of mkfs I run (each on separate disks), the
    more instances of this warning I receive.

    The mkfs's all progress at the same rate. The warnings
    occur as all mkfs's are "writing superblocks and filesystem
    accounting information", near the end of the mkfs.
