[dm-devel] a question about multipathd and udev

[dwu]

If a block device is added, the udev will run the command multipath to 
add the path to the mp if possible.
Why multipathd also process a path addition event:
 (!strncmp(uev->action, "add", 3)) {
        r = uev_add_path(devname, vecs);
        goto out;
    }

Thanks.
