    Hi,

    I found devstat is not widely used in the device drivers. Based the
    grep result of 'devstat_new_entry', it shows only cam, ata, fd,
    geom_disk are using it. In my workstation, the output of 'sysctl
    kern.devstat' shows:

    kern.devstat.version: 6
    kern.devstat.generation: 229
    kern.devstat.numdevs: 2

    I am wondering if devstat can be replaced by the sysctl nodes %desc,
    %pnpinfo etc that jhb introduced. Almost all the information devstat
    can provide can be also exposed by such sysctl node.

    I have plan to introduce a new node named status so that userland can
    disable on individual device. Before that, I want to understand some
    related stuffs.

    Any comments about this?

    Howard Sue
