[dm-devel] a question about multipathd and udev

[dwu <dwu redhat com>]

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.
