Dear Neil,

 Due to the mail content type, so i resend mail again, sorry.

 Here has a little problem about zero superblock on a non-exist
device. We can reproduce this by the command:

  mdadm --zero-superblock /dev/sdgg

   The problem comes from Kill always return 1 when there is no such
device, and the while loop in mdadm.c is waiting for rv == 2. So it
just keep looping.

Thanks.

Best Regards,
KueiHuan-Chen
